Mad scientist Roger (Bruce Dern) has a secret, which he is keeping especially from his wife Linda (Pat Priest). He is conducting strange medical experiments on animals, grafting a second living head onto their bodies. Meanwhile a psychopathic murderer Cass (Albert Cole) has escaped from the asylum. He reaches Roger's home and wrecks havoc. Finally Roger and his assistant Max (Barry Kroeger) gun him down... then of course Roger and Max decide that they now have the perfect opportunity to take their experiments to the next level...
They graft Cass' had onto the body of huge but simple Danny (John Bloom). Naturally the creature escapes and begins a killing spree. The police are assisted by one of Roger's friends Ken (Casey Kasem - yes that one!) Roger and Max are also out to hide their evidence. As for Linda, well she gets attacked and menaced by the monster and ends up put in a cage by her husband. I suspect their marriage doesn't have long for this world...
A cheaply made piece of drivel. The film is fun (for all the wrong reasons of course). The story is pretty much by the numbers and the two headed effects rely on clever camera angles or puppets. Albert Cole is superbly and completely over the top as the paychopath.
