Synopsis:
Ralph Dibny is invited onboard a cruise ship to solve the mystery of a compass that points in the wrong direction temporarily on each cruise. Ralph watches over the compass and spots a gang of crooks move it. He apprehends the crooks, who are jewel smugglers. The next night, Ralph stakes out the compass again. The needle points to the jewels. Ralph catches the ship's cruise director in the act of taking them, proving that he was part of the gang.
