“Delving into new, strange fields of mystery!”
Dr. Janos Rukh discovers a certain type of radium that has almost magical healing properties. But the element has a dangerous side, too, and it has already started affecting Rukh. Consumed by paranoia, he begins to suspect that his wife is having an affair. Wild for revenge, Rukh hatches a deadly plot...using his own poisoned body as a weapon to kill.

**Peak Classic Universal Horror** A bunch of big stars with a well written story, for the time. Bela Lugosi and Boris Karloff are both great and so is Francis Drake. CW: There are racist bits, typical portrayals of Africans for the time period. So watch out for that.
