Ghost Diver (20th Century Fox, 1957)
Roger Bristol (James Craig) is the star of a popular TV adventure series. To further boost his ratings, Bristol promises his viewers that he will locate a sunken treasure off the coasts of South America.
True to his word, Bristol, his secretary Anne Stevens (Audrey Totter) and his skindiver son Bob (Lowell Brown) embark on his dangerous quest, using the cryptic messages carved on an ancient idol as his guide to the treasure.
Their mission is threatened by a covetous local diver (Nico Minardos), who will stop at nothing to get his hands on the treasure. (allmovie)
