A scientist invents a serum that keeps a dog's head alive after its body dies. When the scientist dies of a heart attack, his crazed assistant cuts off his head and, using the serum, keeps the doctor's head alive and forces it to help him on an experiment to give his hunchbacked nurse assistant a new body.
