A young boy, Pete Morgan, is on holiday in the Caribbean with his parents. They are staying on their boat called the Summer Sun. One day his mother is showing him a history website. Pete thinks history is boring and wants to learn Chinese instead. Later, he goes to the beach with his metal detector and finds an old knife. He doesn’t know it but he is being watched by a pirate. His mother and father go shopping in a nearby town and while Pete is writing some e-mails on the boat, the pirate, Tom Carter, comes on board.
