The guys arrive in Arizona, 1547, as a technician named Nimon kills a scientist. After a shootout, he flees into the Tunnel. Nimon is a spy who has planted a nuclear device in the complex. The guys need to find Nimon to get him to reveal the location of the bomb. They lure him in with a fire but he slips, and the Project transfer Doug and Tony after him to 1,000,000 A.D. Nimon is already there and has established himself with the ruling clique . The guys get the info on the detonation time, bypass a force field, and with the aid of a local female "defective" manage to get to Nimon. The Project transfers everyone, including two of the future-types, back to 1,000,000 B.C. After some running around from dinosaurs, they rescue Nimon from a quicksand pit in return for the location of the bomb . The head alien eventually comes around and forces Nimon to give the location of the bomb which they defuse. Everyone ends up in a giant bee hive and the Project gets everyone but Nimon out.
