The Four Skulls of Jonathan Drake

Anthropologist Jonathan Drake (Eduard Franz) believes that the men of his family have been cursed for generations by the native South American tribe he studies. Shortly after his brother, Kenneth (Paul Cavanagh), discovers one of the tribe's shrunken heads in his house, he's found murdered and his head goes missing. In pursuit of the tribesman Zutai (Paul Wexler) and a rival scientist (Henry Daniell) who has become a part of the tribe, Drake attempts to end the curse once and for all.
