Based around a series of comics by manga auteur Eiichiro Oda, it follows Monkey D Luffy, the leader of a group of pirates travelling the world on the hunt for a mysterious treasure known as the One Piece. Along the way, they engage in battles with the government and their fellow pirates, using powers gained by eating "Devil Fruits".
