In 1941, a
Capelis XC-12 transport aircraft flying between Cuba and Puerto Rico runs low on fuel and is blown off course by a storm. The pilot, James "Mac" McCarthy, cannot pick up any radio transmissions over the Caribbean except for a faint signal. After crash-landing on a remote island, passenger Bill Summers and his
valet Jefferson Jackson, take refuge in a mansion owned by Dr. Miklos Sangre and his wife Alyce . Jackson, frightened by his surroundings, is convinced the mansion is haunted by
zombies and confirms this with some of Dr. Sangre's servants. The stranded group becomes aware that mysterious events are taking place in the mansion. The group stumbles upon a
voodoo ritual in the cellar conducted by the doctor who is in reality a foreign spy trying to acquire war intelligence from a captured US Admiral whose aircraft had also crashed on the island. McCarthy falls under the doctor's spell but Summers comes to his aid. When Summers stops the ritual, the zombies turn on their master. Sangre shoots the pilot but falls to his death in a firepit. With Sangre dead, all the zombies are released from his spell. ==Cast==
