[5] Steve Kent's boat is repossessed in Macao, leaving him without a way to make his living as a deep sea diver.

At a casino, he is introduced to wealthy and beautiful Vivian Craig, who at first seems interest in Steve romantically, then lets him know that what she needs more is his diving expertise.

Agreeing to search for medical supplies lost in a plane crash, Steve goes underwater and locates them.

He offers his wife and Steve a three-way split to retrieve the bullion, but after double-crossing them, Allan gets his comeuppance when the boat explodes.

The original cast announced for the film was Märta Torén, Dick Powell and Robert Douglas.
