With Dr. Cooper dead, Jamie must sneak past the Alex 7000 computer to try to stop the doomsday device. But Alex was programmed to win at any cost, and throws all his deadly resources into an attempt to kill Jamie, while also jamming the communications between the OSI and a B-52 which has been sent to neutralize Dr. Cooper's bomb with another kind of atomic weapon. If the plane drops its payload, armageddon will be back on, and only Jamie can stop it!
