What secret lurks 20,000 feet below the waves in the paranormal realm called the Bermuda Triangle? That's the question a scientist (Burl Ives), his student (Carl Weathers) and a young man (Leigh McCloskey) haunted by nightmarish memories of his Bermuda childhood ask themselves. The answer involves a beauty (Connie Sellecca) who has sold her soul for eternal youth and a giant sea turtle that leaves death in its wake. Eerie and hypnotic, The Bermuda Depths was produced by Arthur Rankin, Jr. and Jules Bass (The Year Without a Santa Claus), who meld their imaginative fantasy style with the live-action horror genre.
