Bloodlust!

Four young adults - Betty Scott (June Kenney), Johnny Randall (Robert Reed), Pete Garwood (Eugene Persson), and Jeanne Perry (Joan Lora) - vacation together at sea before landing on a tropical island where they encounter Dr. Albert Balleau (Wilton Graff). Balleau, a sadistic hunter who has a passion for hunting both animals and humans, makes the group his prey. The couples try to escape, but their attempts are thwarted by Balleau and his henchmen.
