Six GIs stationed in Asia secretly photograph the arcane rituals of a group of cobra worshippers. At the climax of the ceremony, the cult members turn themselves into snakes. The high priestess catches the soldiers spying and throws a curse upon them. This off-beat horror film follows what happens to the men after that. Soon after they return to the US, the vengeful priestess follows them and people begin to die from snake venom poisoning, adding credence to the strange tale told by a surviving GI to the police, who become less skeptical as more evidence is unearthed. More trouble follows when the serpentine goddess falls for the ex-soldier's roomie.
