As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally gained the power to stretch like rubber...at the cost of never being able to swim again! Years, later, Luffy sets off in search of the "One Piece," said to be the greatest treasure in the world...

Luffy and crew must contend with "Saw-Tooth" Arlong and his nasty Fish-Man pirates, who specialize in using mafia tactics to squeeze the lifeblood from innocent villagers. Needless to say, it comes as a big surprise to everyone that pirate-hating Nami is actually a member of Arlong's crew!
