Dr. Bernard Adrian is a kindly mad scientist who wants to cure a young woman's polio. He needs spinal fluid from a human to complete the formula for his experimental serum. Meanwhile, a vicious circus ape has broken out of its cage, and is terrorizing people. While it has it's flaws, this movie stars the legend Boris Karloff and is a nice addition to any horror or Karloff movie collection...plus it can be found for only a buck! How can you beat that?
