When Peter gets his hands on a treasure map, it's his big chance to prove himself. But the only ship which will take him to the island is a pirate ship with the weediest, most pathetic pirates to ever sail the seven seas.

The year is 1603, and Peter is a cabin boy -- on a ship full of pirates. But something is wrong. These pirates don't plunder -- they blunder. So Peter has to teach them how to behave like 'real' pirates.
