Tom wakes up in a room alone and no one is there to answer him. It has been 3 weeks and all he can think of is eat, exercise and sleep. On the 20thday the door opens and he is angry over Teresa. Tom question Rat man and he relies by saying that the end result will justify their doings. He explains that Tom’s behavior is the blueprint of antivirus. There is a term used for people like Tom who are immune to flare they are called Munies. He asks Tom to clean up and meet his friends and Killzone is their brains. He does mention there are only few who are immune to flare but does not disclose their names.
Then he meets his friends. Teresa is happy to see him so she holds his hands and he discards it as he is angry over her but his friends take the action as embarrassment leading to not holding her hand. Rat man enters telling them they are willing to give all of their memories back. There are only three people who disagree in getting their memories back namely Minho, Newt and Thomas. Thomas is glad that the telepathy will end. It is only a small surgery that is required to get their memories back. Then rat man says there are two groups among the survivors those who have flares and munies. Through the listing they come to know that Newt is not immune and Thomas is shocked. Then when all agree except these three they decide the first chance they get they will run escape from this place.
All of them enter and there are only 6 remaining and 3 who said no. Then Tom sees Brenda in green doctor’s gown. She comes to him hugs him says not to trust anyone except her and Dr. Paige. While both are happy to see each other she is ordered back to operate. Although Teresa starts questioning Brenda Tom is happy to see her. The three who refused are put in a room for tomorrow. They refused and they are taken as hostage. Tom tells Minho and Newt what Brenda said and then they eat and sleep.
Tom dreams about mom. He is eating cereal and his mom is telling him that he is smart and immune and he will not have to go through what his dad went through. Then next morning 5 guards and Rat Man comes and he says it does not matter if they want it or not all of them are receiving their memory back. Realizing this is their only chance they try to escape but are over powered and Thomas is the first one to enter into surgery and he sees Brenda is the doctor for his surgery.
Thomas gets the hint that Brenda is with him. She tells him to trust her and what she did was her job and she is also immune like him. Brenda acts like she tripped and sedates a guard. Then attacking a female guard they escape and Rat man is electrocuted. They take female guard as hostage and while leaving they count to 3 and suddenly lights go out and siren blares. They are in weapon room and Newt leaves for a while and comes back with envelope and letter asking Tom to read it when the time is right.
They reach the Berg room to see Jorge already hit by Teresa and group who have escaped. While climbing Tom and Brenda get hit. Tom wakes up to Brenda on his side where she mentions that all of the things that happened in tunnel is true. Her father was indeed killed by WICKED and she joined WICKED. She met Jorge in Immune meetings and he is the guardian figure to her. She consoles him saying may be Teresa is not so wrong and kisses his cheeks.
They reach Denver and are in a mall and some guy from right arm slips a paper with address to them. It is a note from Gally. Brenda and all are looking for Hans who worked for WICKED and is retired now who can remove the chip from their brains. They meet Gally where he mentions he was being controlled and he acted crazy so that they would set him free. The group comes to know Teresa informed Gally that they are coming and there is a bounty in Hans name. He also mentions that those who are immune have reduced to half in past six months and is not a coincidence. They have vanished into thin air.
They meet Hans and before removing the chip Tom attacks however they are able to remove the chip and Tom has lost telepathy. While they are drinking coffee they are attacked. Tom is taken by people who want money instead of him. Van is attacked by rat man and they escape and when they reach Berg they realize Newt is gone. Tom reads the letter of Newt “KILL ME IF I WAS EVER YOUR FRIEND”. Next day they are attacked and they run in a van. Right Arm saves them and come to know that Right Arm is planning to destroy wicked by demolishing their building. Tom is going to plant in WICKED and Brenda is staying back they part by saying “be careful” “don’t kill yourself”.
To finds where Newt is that is with other infected by flare and Newt is mad because Tom did not do one thing he asked for. Newt attacks and Tom shoots him on the head.
Tom is captured in the WICKED building. The last part of the cure is to remove his brain tissue and analyze them. HE wakes up to see Ava Paige and she tells him about the letter and a map to exit from here. He leaves and meets with Gally, right arm people, Teresa, Aris and Brenda and all. They plan on saving all they go to the maze. While rescuing they get attacked by grievers and they hear WICKED being blasted and the buildings falling down. He reaches the maintenance room as per the map and sends people through flat trans. Then Tom is attacked by Jenson (rat man). They fight a lot and he is so consumed in bloodlust he keeps on hitting the dead Jenson. Just in a flash Teresa gets smashed into a falling ceiling killing her instantly. Lastly, Tom, Brenda, Minho enter flat trans and close the gate.
The place they enter is a paradise. There is Natural River, ocean, hills and many more. He goes to hill top to observe sunset. Brenda joins him saying it is better for the future generations. He does not question her but holds her hand. In return she kisses his cheeks then lips and hugs him. He promises in his mind that he will not tell anyone about killing Newt. HE pulls Brenda closer to him.
Ava Paige emails all saying how to control the population they leaked the virus and how new test subjects a trials was unnecessary. It was a brutal method. The remaining immune people are precious for future and should not be wasted. WICKED was established for better future and she is glad two immune people helped her achieve the goal. She is happy about the new beginning and WICKED is good.
I loved the whole concept how the virus being spread to control population (somehow I can imagine that this may happen in the future). Sad about Newt being dead and happy about Teresa dying. Very happy about Tom and Brenda. A new beginning is a good start.
