On a visit to a seaside town in Australia, fifteen-year-old Sam meets Annabel, who works at the local museum. Annabel's interest in history is infectious, and Sam soon finds himself eager to hunt for the remains of a boat called the Mahogany Ship, a shipwreck sought after by many. When a storm creates an erosion hole that exposes a structure, Sam and Annabel are convinced it's the fabled ship. Soon all of the museum staff are at the erosion site to check it out. But the same storm also destroys the museum's power; someone knows the alarms aren't working and steals the museum's most treasured artifact, a large porcelain peacock worth $4 million. As Sam and Annabel search for the thief, they realize there may be a link between the fabled shipwreck and the recent theft.
