Research scientist Scott Nelson (Robert Lansing) discovers the secret of passing through solid matter when he accidentally opens a fourth dimension thanks to an electric motor stirring up his brainwaves.
Entering a sordid life of crime due to his power, he must keep replenishing his life force in a vampiric fashion by passing through the bodies of others or else suffer from premature ageing.
Alerted by Nelson’s assistant Linda Davis (Lee ‘Catwoman’ Meriwether) and his brilliant but irresponsible scientist brother, Tony (James Congdon), the police pursue Nelson but can neither kill nor trap him since he can escape by simply walking through walls.
Finally, Linda permits him to trap her – loathsome as he has become – so that she can kill him. She empties a revolver into his body, but he does not die. He passes into a wall made of a metal impenetrable to all but himself and vows to lurk inside the fourth dimension and emerge at another time for revenge.
Passable special effects make this novel effort from The Blob (1958) team reasonably engaging despite some overwrought acting and plot inconsistencies. A romantic triangle sub-plot between Nelson, Linda and brother Tony is yawn-worthy.
Released in some markets as The Evil Force.
