If ye values thy immortal soul, open not this accursed chest. So reads the inscription on the 400-year-old metal box found by teen psychic Jessica Burns (Carolyn Kearney) on her Aunt Flavias farm. Although archeologist Gordon Hawthorne (William Reynolds) warns it should remain untouched, two greedy ranch hands break it open, believing there's treasure inside. What they find instead is the living head of executed devil worshipper Gideon Drew (Robin Hughes), the foulest and wickedest man to ever set feet upon the earth. Condemned to a living death until he's rejoined, Drew hypnotizes Jessica into unearthing his body so he can spread hells flames around the world. A terrifying tale from the Atomic Age of horror movies, the Thing That Couldn't Die is a devilish gem that's a head above the rest.
