There are a few decent moments in this colorful adventure that was a brief return to 3-D. The credits indicate the use of the gimmicky effect, but not much else, in a standard melodrama of greed and lust. She may have been pushing 40, but Joanne Dru is as enticing as Marilyn and Sophia and Liz in her tight bathing suits, involved in the search for gold off the coast of Majorca. Along with the ship's caretaker and sole crew member, Asher Dann, she's aboard with gold seekers Mark Stevens and the bullying Robert Strauss, a character so vile that any self-respecting shark would have spit it out upon attempting to swallow.

The underwater sequences are beautifully filmed, and there's an encounter with the Portuguese man of war that's pretty scary. But really very little happens, and that's adult adventure especially when you're waiting for something to pop off at you in 3D and that doesn't occur. Dru pretty much is the only decent acting in the film, although Dann's character seems to be the only man aboard with any scruples, even though his pass at Dru is presented awkwardly and out of step from his previous actions. Jean-Pierre Kérien is seen recurringly throughout as the ship's real owner, mainly in phone calls, indicating that Dann wasn't as honest as the script insinuated. Pretty much a let down, and frequently just dull.
