A blind man who uses bat-like powers of echolocation to navigate his surroundings; a samurai with reflexes faster than a speeding bullet; a man who's immune to electrocution.

Monkey glands for immortality, hypnotized assassins, and a brain-linked cyborg couple. We investigate some of the strangest experiments on record. From two-headed dogs and testicle transplants...These are the bizarre but real experiments that boggle the mind. Prepare to be astounded--and a little grossed out.
