Tony Curtis introduces a triple bill of classic horror films. In 'The Ape Man', crazed scientist Dr Brewster (Bela Lugosi) slaves away in his basement, hidden from the outside world, determined to produce a serum based on a gorilla's spinal fluid. When Brewster tries the serum out on himself, he first develops a thick growth of facial hair, then discovers that his spine is contorting into the posture of an ape... In 'The Ghoul', an eminent Egyptologist (Boris Karloff) instructs his servant to bury him with a precious stone that will bring him eternal life. The stone is stolen from his body and he returns from the tomb, in search of revenge. In 'The Indestructible Man', after a multiple murderer (Lon Chaney Jr) is sent to the gas chamber for his crimes, his corpse is subsequently re-animated by a mad scientist (Robert Shayne). The killer then goes on the rampage, determined to exact a grisly revenge on those who sentenced him to death.
