Billy "Big Bang" Blitz is a sergeant in S.A.B.R.E. (Special Assault Brigade for Real Emergencies). He is contacted during a vacation at the beach with his girlfriend Mary to save Professor Plum, creator of a Doomsday Bomb capable of destroying the world. Bang soon encounters Tom Guycot, the skeleton mastermind behind the abduction, and he learns that the Doomsday Bomb is controlled by six medallions which have been distributed among the seven governors of Demonhead. On his journey, Bang encounters Michael, who claims to be Bang's ally and tells him about a grieving sprite. Upon meeting the sprite, he learns of a captured hermit who teaches Bang various force powers upon rescuing him. While searching for the rest of the medallions, Bang repeatedly experiences strange mental discomfort.
