 Jimmy Olsen finds a bottle with a written message but seawater has washed away the ink. Clark Kent, using his enhanced vision, can make out the name "Golden Vulture," which is the name of a ship that has docked at Metropolis. The message was written by a member of the crew desperate to flee the vessel. Jimmy and Lois Lane board the ship to do a story but are captured when they find out too much. Clark, meanwhile, using his X-ray vision now knows that jewels and diamonds are being sent *to* the ship, which has supposedly found treasure in the Carribean. Clark gets aboard but is captured because Lois and Jimmy prevent him from changing into Superman. Clark is forced to walk the plank but Superman turns up moments later to put an end to the plot.
