When a mysteriously deformed man, Eric Jacobs (Eddie Parker in an uncredited role), is found dead in the desert, Dr. Matt Hastings (John Agar), a family doctor in the tiny neighboring town of Desert Rock, is called in to examine the body. Jacobs, a research scientist, worked with Prof. Gerald Deemer (Leo G. Carroll), a reclusive scientist who's conducting mysterious experiments at an out of the way mansion near the town.Dr. Matt is baffled by the cause of Eric's death.

She also gets to know Matt, who...
