Private Luc Deveraux and his sadistic sergeant, Andrew Scott, got killed in Vietnam. The army uses their bodies for a secret project - reanimating dead soldiers as deadly obedient cyborgs. However, their memories come back too.

The "universal soldiers" must fight the whole army, when the military's supercomputer S.E.T.H gets out of control.
