Adventurer Jim Brennan (Flynn) finds a fortune in smuggled diamonds, which he hides in a hotel room. Unfortunately, he's deported before he can retrieve the gems and it takes him five years to make it back to Istanbul. Then he's hounded by the original smugglers who want their gems back and discovers his lost love Stephanie (Borchers). Cole croons a couple of songs in his role as a lounge singer. Remake of 1947's "Singapore."
