The story begins with Connor, the typical bad boy. Connor is chosen to be unwound by his parents due to his misbehavior. He decides to run away and asks his girlfriend to come with him. She accepts but later backs out. He then decides to run away on his own.
Connor is caught while running away and meets Risa and Lev. When Connor is in the police car, the car almost crashes with another vehicle and he manages to escape. He approaches the car where Lev is in and drags him out the door which leads to them fighting. A bus comes and tries to avoid them, causing it to crash. Risa jumps out of the bus and as Connor goes to follow her, he takes Lev (who is unconscious) with them.
They then decide to go hide in a school. They've found a baby while escaping and go to the bathroom to hide. Lev, who secretly wants to be unwound due to his religious reasons, goes to the office to turn Connor and Risa in. He calls his pastor, who is angry at him for calling him, and he encourages Lev to save himself and not be unwound. So he pulls the fire alarm and escapes.
A shop owner helps Connor and Risa escape by sending them to "the Graveyard" with other Unwinds. Risa warns Connor of a specific Unwind, Roland. She explains that he wants to kill him. Lev comes back and stays with the group. The leader of "the Graveyard" gets injured and is taken by Connor, Risa, and Roland to the hospital. Roland turns Connor and Risa in but gets himself in trouble as well.
The three get sent to the Chop Shop to be unwound. Roland is unwound and Connor is next. Lev, who joins a strange cult called the Clappers, does not clap to his death and goes to save Connor and Risa after the Clappers blow up the facility. He is later thrown in jail unfortunately.
Connor loses his arm and Risa is paralyzed from the waist down. Connor gets Roland's limb and gets a new identity to prevent from getting unwound. Risa cannot be unwound due to having paralysis. Connor returns to "the Graveyard" to start a revolution with the remaining Unwinds.
