A hideous monster from beyond the grave! A small California mountain community is terrorized by a murderous monster that is stalking the townspeople and savagely murdering them. The undead thing is believed to be the incarnation of an infamous Spanish Conquistador who was killed in the mountain during an Indian raid. Filmed in scenic Big Bear, California, this drive-in thriller is the first film effort of '50s cult filmmaker Richard Cunha and one of the last films of monster make-up artist Jack Pierce (Frankenstein, The Mummy).
