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 Whitebeard injured, the Navy launches a counterstrike to finish the pirate rebellion once and for all. And as the three Navy Admirals stand in his way, Luffy will need one last trick if he hopes to save his brother Ace from being executed.
