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...

With their queen dead, the people of Fish-Man Island carry on her will and hope to one day achieve her dream. But Hody Jones and the New Fish-Man pirates have other ideas, including ruling the kingdom themselves. The fate of Fish-Man Island will rest on Luffy's shoulders, but will he destroy it instead?
