Plot[]
Will hears the alarms and asks a nurse if they're being attacked by Robots. She tells him she doesn't have any information and they shouldn't overtax his new heart. "We're being attacked by Robots," says Penny, entering. Judy and Robot enter and Will gets a summary of everything that's been going on. He asks what they're going to do, but Judy tells him to stay in bed. They all agree that this is probably for the best. The Robot places his hand on Will's heart. "We both have mechanical hearts now," agrees Will.
At the control center, the powers-that-be discuss recommendations to handle the dam situation. Don tells them he was there and his recommendation is that they don't have enough time to get the turbines repaired. Maureen says that they need to replace the turbines, that they're just things that spin and anything that spins can generate energy, like a Jupiter spacecraft's vertical take-off and landing engine. Don agrees it's a good plan and Maureen says they need to get the Jupiters there. The chancellor wonders if the ships will still be spaceworthy and Maureen says there's no going back. The chancellor asks about the alien engine, saying that she can't gamble on this. John tells her the Robots are relentless and that they can't use their engine because they will find them. It's what got them into things in the first place. He says they have to use their own tools.
Thus, the plan goes forward. John, Ava and Grant Kelly direct the grounding of the Jupiters and getting everything cabled together. Up above Alpha Centauri, the Robots begin their final approach. Dr. Smith wanders the medical facility when she is spotted by the Robot. She arrives in the room containing Captain Radic. In the control center, Maureen reports that everything is on pace. Dr. Smith comms her, asking what their odds are. Maureen tells her everyone is working hard to increase them. She starts to bid Smith goodbye, but Smith pleads with her to tell her whether they're going to make it or not. Maureen tells her that as a girl she spent nights looking at the stars, but getting there seemed impossible. She says their odds are worse than usual, but they're going to make it. Smith tells her that it's all she needs to know.
Smith walks up to Radic, needle in hand. She speaks to Radic, saying he has to understand that if they believe Maureen, the sun will rise on a patch of land that's all hers. She says it's her only chance and moves to inject him. "Help, Dr. Smith," says the Robot. Smith asks who he means, telling him not to say "family," that she doesn't have one. She tells him the answer is no, but he simply repeats his words, holding out his hand. Meanwhile, Judy leads an evacuation convoy. She calls in for a report on Will's status and the nurse tells her he's holding steady. Penny asks if anyone has any idea where they're sending them and Samantha says she heard that it's a copper mine. Vijay chips in that it's also where they stored the nuclear waste. "How nuclear is the waste?" Liam Tufeld says that they should be chipping in, that the powers-that-be don't recognize their excellence. "I agree," says Vijay. "Didn't we save all our parents?" Penny says that they did, but then they ran away from Robots, that they're good at running away.
The team plugs in the last of the Jupiters. With minimum power activated, the control center begins activating the shield. They reach 65%, but the Robots, instead of pulling away, accelerate. "They're trying to squeeze through," realizes Maureen. John plugs in the last Jupiter and they reach 90%, but it's not enough. A Robot vessel makes it through. An alien screeching noise comes through and the chancellor asks what it was. "It means our radios are useless now because the Robots are here," Maureen tells her.
Will's doctor, inside his evacuation Chariot, leaves to try to help anyone who may be injured. She tells him to stay put. The Robots emerge from the wreckage of the crashed spaceship. It's chaos for the evacuees as they realize the Robots are coming. Will assesses the Robots, seeing a new set of lights on one of their faces. He realizes that they want the engine, but wonders to what end. He has a flashback and comes to a realization - that it was the alien engine that caused the damage to the shattered planet. He recalls SAR saying that he killed the Robot Builders and calls out, saying that they need to keep the engine away from the Robots. He shouts for them to stop, but in the panic, nobody listens. He disengages from his IV, despite the warnings of risking critical heart failure. Seeing him, Penny races to him. He explains to her what he realized, that the engines rip holes in space and that when sitting on a planet, they destroy it. Penny says she's going to get Judy, but Will tells her there's no time, that it has to be her. She says she can't, but he says he knows her better than she knows herself, that she's stronger than she thinks. "You can do this," he tells her. She sighs, but agrees, telling him to stay.
Penny heads forward, telling herself she's just going for a little stroll, that it's just like in the brochure. She mutters that she's invested so much time trying to not to touch alien objects, yet here she is. She reaches the engine, only for Judy to show up, saying that she's trying to help injured people, only to see her wandering through a disaster area. Penny explains the situation. "Quit explaining," let's do it, Judy tells her, as they carry the engine in the hope of keeping it away from the Robots. They pass by a stuck Robot. Judy tells Penny not to worry, but the Robot seems to look at Penny almost pleadingly. Judy shouts after her.
"You're dying, aren't you?" realizes Penny. Judy tells her to leave it, but she goes back, telling the Robot she won't hurt it. She lifts a large piece of metal off of it. "I'm Penny Robinson, by the way," she tells the Robot. It rises and she says she doesn't want any trouble. "So this is how the book ends," comments Penny, but the Robot does not attack. It stands up and flexes its arms. Liam, Vijay and Samantha watch as the Robot stands before Penny, looking more human like Will's Robot and the lights on its face now blue. Penny asks if it has a name, saying that "Robot" is already taken. She asks if she can call her "Sally." She explains to the others that she helped Sally, that she thought that she has people to her, but the Robots don't. "Come on, we gotta help them too," Vijay tells her.
Judy proceeds on her own with the alien engine, only to be confronted by a Robot. She picks up a rock, saying she won't make it easy. Just then, however, the others arrive with a whole group of rescued Robots. Judy says that she doesn't have the words, but Penny replies that it's her department. Will stares in wonder, saying that it changes everything. "Help Will Robinson," says the Robot. Vijay walks up to Penny, saying that he needs to tell her something: "I told you so." She kisses him. "You've gotten better at it," she tells him. "Trouble, Penny Robinson," Sally tells her, indicating the arrival of unfriendly Robots. She says they need to keep the engine away from them. Sally and the others move to defend. The battle begins, a fearsome fight. A Jupiter arrives, with the Robot, who comes to Will.
The Robot places his hand over Will's heart. Will agrees that it's bad, saying that he had a lot of work to do. "Yes, Will Robinson," agrees the Robot, bringing Will aboard the ship. "So, who's flying the ship?" asks Will. That turns out to be Dr. Smith, who says she's perfectly capable, assuming the flight manuals she read were up to date. They take off and Will broadcasts to Penny and Judy, saying they're coming to get the engine. "We are?" wonders Smith. Judy tells Will not to approach, that they'll be shot out of the sky. Will tells Penny that she gave him an idea, a big one. She asks if their parents know.
Back in control, they see the Robots fighting each other. Will comms them, telling them that Penny and Judy have the engine and it has to be kept from SAR. Maureen tells him he can't go off alone, but he says that he's not, and that he thinks he finally knows how to end the war. He says that Penny just proved that what he has with the Robot isn't a fluke, that every Robot can be free. "Somebody just has to make them see that." He tells them to hold on until the Robot gets back. "What about you?" asks John, and he tells them to cross their fingers. Maureen says that his heart can't take the strain, but John tells her he said to hold on and that's what they'll do. First, though, they have to get Penny and Judy out of there. Smith asks Will just where they are going.
The battle between the Robots continues and it looks to Judy as if their side is losing. John broadcasts, saying that they're coming to get them and the engine out and to meet them at the main road. The group rushes aboard the Jupiter 21 chariot. John says that they need to find somewhere to put the engine that the Robots can't get to. Don suggests that they "plug the in into the out," something he had earlier chastised a fellow engineer for. The Jupiter 2 arrives at an Earth-like planet, which the Robot calls "home." Smith asks if it's likely there are other Robots there and Will agrees that there'd better be. "You're one of the them," Will tells the Robot. "They'll listen to you." He tells the Robot he knew he wouldn't come without him, but that he has to finish it, to tell them everything.
Back on Alpha Centauri, the group hides the depowered engine aboard the Jupiter 65, running cold. Don tries to plug "the in into the out," in the hopes of electrifying the Jupiter, only to get blasted back. "Slight hiccup," he tells the others. As he struggles to find a tool, the Robots close in. Judy tells Don that if he has any tricks, now is the time. He finally finds what he needs and tries again, electrifying the Jupiter just as the Robots climb atop it. The trick works perfectly, frying a number of them. Maureen comms, telling him that they're good. Don spots more Robots and says they won't give up because the others got zapped. John tells him he's done all he can and to find cover. "See you on the other side," he agrees.
Maureen summarizes that the electrical field will hold until the fuel powering the Jupiter runs out and John says that it's up to Will now. Dr. Smith tries to rouse Will, telling him that they're there, but the Robots don't seem too happy to see his Robot. She tells him that the Robot is drawing pictures, the story of him and Will, and a picture of Penny doing the same thing that he did. She tells Will that the other Robots aren't listening, that they're leaving. With the Robot by her side, Smith asks if there's anything he can do. The Robot heads out in a storm, Will by his side. He lays Will in a hole in the ground and places his hand over his heart. "Trust, Will Robinson," he tells him. He extends himself like a protective case over Will and lightning strikes. Will looks up to the see the Robot crumbling away into ash. He gets up, gasping in horror at the loss of the Robot, crumbling the ash in his hand. "What did you do?" he wonders. Smith comes over and Will asks her why the Robot did that. "You know why," she tells him, holding out her hand to take him back to the Jupiter. He tells her he can still feel him, as one of the Robots watches from above.
Back on the Jupiter, Will tells Smith the Robot's last words. She suggests that maybe he was trusting them to go on without him. Will tells her that according to the computer, he's completely healed. There's a piece of Robot inside him. Smith agrees that he put it there when he put his hand on his heart. "He saved me," says Will and Smith agrees, saying that he saved her too, that she was about to do something she could never go back from. She thought he was asking for help, but he knew what she needed, and has always known what they both needed. They hear Robots whirring outside. "It's a command," Will tells her.
On Alpha Centauri, the primary fuel supply on the electrified Jupiter runs out. The computer reports that the fuel reserve is as 10% and dropping. Grant chats with John, thanking him for keeping him alive for Judy. John tells Grant about writing his resume on a piece of cardboard with strawberry markers. He says Grant was first in a lot of things and he had some big shoes to fill. Grant says that all the first don't compare to what he missed. The fuel runs out and the lights go off. The Robots quickly attack and Grant drives Penny and Judy away, while John and Maureen carry the engine to another Chariot. As the Robots fire missiles, John suggests that he and Maureen eat at an Italian restaurant when everything is over. They take a hard hit and the Chariot is upturned. Maureen shouts for John, then stares at the stars, remembering dreaming of going to space to see them as a kid. She recalls seeing the stars with Will, telling him that she dreamed about going up the stars. She says it's better than she imagined, because it's with all of them as a family.
Maureen gets up, pushing through the pain. The Robots march forward, heading for the engine. She shouts at them, asking if they know Will Robinson. "I'm his mother," she shouts, spraying liquid helium at one reaching for the engine. John swings a rod and it shatters. He goes for another, only to get knocked down. The Robot then grabs the engine. John then receives a message from Will: "Play Me." The Jupiter 2 comes in for a landing and Will emerges. SAR whirs. "Will Robinson," he says. He plays the command sound, and John and Maureen do as well. Judy and Penny approach, also playing it, then Grant, then Smith and Don. SAR wheels around in confusion, screeching. Will tells him he needs to turn the engine off. "No," SAR replies. Will shouts at him to turn it off, but he replies that he will kill masters and the heart. "He's gonna take us down with him," realizes John.
Will turns off his command signal. SAR leaps at him, once again impaling him in the heart. Will recalls the Robot telling him to trust. "He knew you'd go for my heart again," says Will, as a blue light arcs from his heart to SAR's claw. It flows through SAR. "And I trust him," states Will as SAR withdraws the claw. Will tells the others he's okay as SAR reels back, then takes on the form of the Robot. "Robot, is that you?" asks Will. Robot reaches for the alien engine and powers it off. "Safe, family," he declares. Don throws back his head, exhaling in relief. The Robot places his hand on Will's shoulder. Maureen hugs John. "So, less than 24 hours after the Robinsons get here, Alpha Centauri is trashed," comments Penny. "I'm not saying there's a connection, but it doesn't look good." Maureen replies that she sees it as an opportunity to build it better a second time. Don quips that he could use a hug right about now.
Penny sits a table, writing in her memoir. She states that it's her job to write the epilogue, that as jobs go, it's pretty easy. She explains that Maureen is in orbit, building another spaceship to replace the Resolute, assisted by super-advanced beings whose technology still seems like magic, and Don. She explains that when the Robots were freed from their programming, they could do what they wanted. Most left without saying they where were going, with all them different now that they're writing their old commands. Sally too, left almost immediately, disappointing her until she realized that she's just a girl too finding her place in the universe. She says that she's never seen John this relaxed, that more than anyone else, soldiers appreciate the value of peace. Judy has finally realized that she has nothing to prove to anyone. She says that she hasn't seen Dr. Smith for a while, and it makes her nervous.
Smith pays a visit to Captain Radic. She sits down next to him, saying that he's looking better. He tells her that she may have gotten rid of the evidence, but he knows who she is and what she did. She holds up some papers and he asks if she thinks he'll fall for the same trick twice. She tells him it's not a trick. "It's a confession." He takes it. She is next seen in a prison cell as Prisoner 002, reading a copy of Sense and Sensibility. A voice tells her that she has a visitor. It turns out to be Maureen. She asks Maureen if she baked her a cake with a file in it. "I don't bake and you don't need a file," replies Maureen. She tells her she was reviewing the passenger list for Solidarity and discovered the name Jessica Harris on it, authorized by Dr. Zoe Smith. She asks who she is. "My sister," replies Smith, saying that it's only technically true, that she's disowned her. "Then she doesn't know you who you really are," replies Maureen and Smith says that she's not sure she even knows who she is at this point. "I do," replies Maureen, saying to look her up when she gets out. She recalls herself staring up at the stars on Earth, Judy telling her that dinner is going to get cold.
On Alpha Centauri, the Robinsons sit down to dinner, including extended family members Grant Kelly, Robot, Don West and Debbie The Chicken. Don apologizes for being late, saying that Debbie got into a fight with a goat. Penny says that everything smells amazing, and they agree that civilization is nice. Will says that he's logged over 100 hours of flight time and won't be alone this time. "Trust Will Robinson" says the Robot, Maureen telling Will to be home by Christmas. They dig into dinner, a wonderful feast.
"Will said 'Don't worry, I promise I'll be home for Christmas'," narrates Penny, continuing that things don't always work out the way we plan. She writes that it's the end... of chapter one. Will narrates that he is Will Robinson of the First Human-Robot Exploratory Group. "I don't know exactly where we are right now, but it's beautiful," he declares, as he and the Robot stare out into the wilderness of a vast, idyllic planet.
