Ten years after nuclear fallout turned insects into monsters, the last of humanity survives in the Bunker. Every night, Cole Wade secretly fights the swarm and brews the repellent that keeps his community and his wife, Rae, alive. She ignores him and pines for Jesse, the Bunker's golden Ranger, who takes the credit for Cole's work. On their anniversary, Cole decides he's done. Seven days before the surface opens, will Rae see what she's losing before he walks out the door?
