At first, Dr. Sidney Schaefer feels honored and thrilled to be offered the job of the President's Analyst. But then the stress of the job and the paranoid spies that come with a sensitive government position get to him, and he runs away. Now spies from all over the world are after him, either to get him for their own side or to kill him and prevent someone else from getting him.

A biker gang visits a monastery where they encounter black-robed monks engaged in worshipping Satan. When the monks try to persuade one of the female bikers, Helen, to become a satanic sacrifice the bikers smash up the monastery and leave. The monks have the last laugh, though, as Helen, as a result of the satanic rituals, is now possessed and at night changes into a werewolf, with dire results for the biker gang.
