King grabs one of the boys and escapes in a stolen car. He is overcome by radiation sickness and orders the boy out of the car. The boy is immediately recaptured. King is pursued by a helicopter, loses control of the car and is killed. Joan and Simon escape by boat, but they are also overcome by sickness. A helicopter hovers above as their boat drifts off course; the pilot has orders to destroy it once the occupants are confirmed dead.
