Episode Summary from Falling Skies Wiki:
The finale episode begins with Pope , Weaver and some other fighters on a train to Chicago. They talk about needing the Volm weapon to work and apparently, the weapon has already been dug out because we see Dr. Kadar trying to make it work. Tom and Cochise are talking and they comment on the fact that more Volm are on the way. Then Cochise urges Tom to “have faith, my friend.” Back on the train, we see that Lourdes is there and she’s chained up and Weaver comments that she is “bait” to lure out the Espheni overlord, Karen.
The train encounters a couple Espheni mechs and we see Pope and Weaver begin to attack. But, the train is just a decoy. The Volm weapon is not going to Chicago, it is headed to Boston on a boat. Tom, Cochise, Mattfro, Hal and Maggie watch as Cadar shoots the weapon at the Boston tower and it hits. It takes a minute, but the tower collapses into rubble. Tom and the others celebrate as they see the defense grid begin to crumble. Moments later, a huge Volm ship arrives on the scene.
It is the night after the Volm have arrived and the humans are celebrating, playing drums and dancing around while Tom is in a tent preparing for his meeting with the Volm leaders. Outside, there is a cheer as Weaver and Pope arrive at the camp. They were rescued from their battle with the Espheni by a Volm brigade. Cochise says his people are happy to help the humans. He tells Tom that he will get to meet the Volm leader tomorrow morning, which is faster than Tom wanted.
At the meeting, the Volm commander begins by shaking hands and acting quite nice. It turns out that he is Cochise’s father. Tom wants to talk about military plans but the Volm say that will not be necessary. The Volm say they don’t need any input or help from the humans. They know how to fight the Espheni and the humans “would just get in the way.” Tom and Weaver are not happy. Tom wants to know what the Volm plan to do with the humans. The Volm leader says they will all be relocated to the south to Brazil.
Tom says there is no way he will let that happen. The Volm leader seems to not care what Tom and Weaver think and says human relocation will begin today. Tom says they want to keep on fighting and then the Volm leader turns to walk away and Tom grabs his shoulder to continue talking, this causes the Volm to fling Tom aside and leaves the room.
Weaver comes back to camp. He orders everyone to get their stuff together and move out. He says they will leave in one hour so they can’t be rounded up by the Volm. Someone asks about Tom and Weaver says Tom is being held captive by the Volm. Weaver goes into a tent and seems to suffer a mild heart attack. His daughter comes in and he tells her that he has been taking pills to keep his heart from acting up. He asks her to keep his condition secret. Before the humans can pack up and leave, Cochise and a Volm military party arrive and order everyone to prepare for transport. Pope wants to fight them, but Weaver realizes they are badly outgunned. Weaver orders everyone to hand over their weapons. Pope sneers at Weaver as he says, “The Volm have just done what the Espheni never could. They’ve brought us to our knees.”
Meanwhile Tom and the Volm Commander are talking. Tom is angry that Cochise lied to him about the Volm plans. The Volm leader says Cochise was operating under strict orders. The Volm leader explains that every other planet they have liberated has contained people who were glad to be relocated and leave the fight to the Volm. Tom explains that humans are different. “Allow us to fight for our freedom,” he pleads. The Volm leader admits that he has never contemplated doing anything but what he always does. He has never had to really consider other options. He tells Tom he will think about it. It is clear that the Volm are not evil, they simply do not understand humanity.
Hal is chatting with the captive Lourdes. She looks terrible and is desperate for the bugs to be out of her brain. Hal vows to help her get better. Maggie says they may have to “put her out of her misery.”
Cochise arrives and tells Weaver it is time for the humans to go to Brazil and they join with Tom. Cochise leads them away and takes them over to their weapons and says the humans are free to go, though he asks them to leave the Boston area. Tom says, “we are going to continue to fight.” Then Cochise says he hopes they will see each other again and he hands Tom a Volm rifle and the humans leave. The Volm commander and father of Cochise thinks the humans will die if they fight, then Cochise says humans are stronger than the Volm think they are.
The humans are on the road out of town and Ben senses something nearby and Lourdes begins freaking out. An Espheni ship is inbound. Karen comes out with some of her forces. She is carrying a white flag and says she can see that the Volm alliance with the humans has gone sour. She says there will be more unpleasant discoveries about the Volm. She tells them that there may be a day when the two sides need each other. She tells Tom she brought a gift for him. Tom says he has a gift for her too. He puts a bullet in Karen’s chest.
The Espheni forces attack but the humans defeat them. Karen is lying on the ground almost dead. She tells Hal she only wanted to be with him and her final words; "I'm sorry". Maggie pulls out a gun and puts two bullets in Karen.
Tom hears Anne in the woods and rushes to her side and Alexis is there too, but she has aged quite a bit because of her alien DNA.
Tom talks to Dr. Kadar about Alexis. The doctor does not know if Alexis will continue aging at a rapid pace. The humans are moving out, then Pope comments that being back on the road feels like old times, to which Weaver agrees. After that, Alexis goes up to Lourdes and touches her face. Suddenly dozens of Eye Worms from inside Lourdes come pouring out of her, and they all gather in Alexi’s hands and she crushes them. She is witnessed by Tom and Weaver.
