In this second Carter mystery, a mysterious rash of cargo ships sinking in Panama leads insurers Llewellyns of London to hire vacationer Nick Carter and his eccentric associate Bartholomew to investigate. Nick recognizes influential nightclub owner Al Taurez as a shady operator, but getting the goods on him depends on slick diversions involving the heavyweight champ of the Pacific Tuna Fleet, a Panamanian bombshell armed with American slang, a young couple in love and a whole raft of crooks and cutthroats.

Trivia, insights & behind the scenes
This was Jacques Tourneur's second feature after years as a second-unit director — his shadow-play techniques here directly preview his later horror masterpieces Cat People and I Walked With a Zombie.
The Nick Carter franchise was MGM's attempt to compete with Fox's Charlie Chan and Warner's Sherlock Holmes series — this middle entry got buried because it was deemed too similar to their own Thin Man formula.
