Mad Doctor of Blood Island

In "The Mad Doctor of Blood Island," John Ashley stars as Dr. Bill Foster, a pathologist investigating a strange chlorophyll disease among the islanders on Blood Island. Sheila Willard (Angelique Pettyjohn) arrives on the island seeking to reunite with her father, while Carlos Lopez wants to leave his mother, Mrs. Lopez, behind after her husband's mysterious death. The trio soon discovers that Dr. Lorca (Ronald Remy) is creating human/plant mutants with chlorophyll blood from local natives, and they must navigate the island's cursed landscape to survive, including a terrifying encounter with a green-skinned monster resembling Don Ramon Lopez, Sheila's father, who has been transformed into the beast after being experimented on by Dr. Lorca.
