Bill Foster, a young pathologist, is sent to Blood Island to investigate the discovery of a human corpse with green blood. On the boat from the mainland, he meets Sheila Willard, who is looking for her estranged father, and Carlos Lopez, who has come to take his widowed mother, Doña Anna, back to the mainland. Arriving on the island, the travelers begin to perceive trouble: Sheila's father has become a hopeless alcoholic, while Carlos' mother, Doña Anna, is now the mistress of Dr. Lorca, who holds the island in his control. A number of ghastly murders have been attributed to green, sub-human monsters. Carlos eventually discovers that the tomb of his father, Don Ramon, is empty, and Dr. Lorca admits that he used Don Ramon to experiment with a chlorophyll drug which he believed to contain the secret of youth. Don Ramon, who has been transformed into a green-blooded monster, kills Doña Anna. Dr. Lorca tries to imprison Bill and Carlos, but Don Ramon murders Dr. Lorca and sets the laboratory ablaze. Bill and Carlos, along with Sheila and her father, who has given up drinking, leave the island, believing that Don Ramon has been killed in the fire.
