The problem is the gold is actually there. Evelyn Keyes tricks him to go hunting for it by fooling him with a false bait: he is hired as a diver to go saving a cargo from a wrecked plane loaded with medicines and drugs, but when the cargo is is saved it is pure gold worth $200,000. She wants to share it with him ignorant of the dangers of smuggling gold around Hongkong, the word goes around, and soon the whole area of smugglers and pirates are interested in their cargo, which they intend to sell in Hongkong, including the authorities and a real pirate, and naturally everything goes wrong, particularly since Evelyn's husband turns up and wants to share the party. In the end everyone double-crosses everyone and almost no one is left alive, some getting hoist by their own petards. It's an ordinary adventure yarn, worth watching for the sake of Jeff Chandler, as it is always a pleasure to find old films with him that you haven't seen before. Prepare yourself for some fireworks.
