The age of buccaneers has arrived. They flood all the seas in search of the "One Piece," the fabulous treasure left by the legendary pirate king Gold Roger. Luffy is fascinated by this world and decides to set sail to one day become the greatest pirate!! Upon arriving at the "Grand Line," Luffy and his companions find themselves clashing with the terrible secret organization "Baroque Works," which plans to overthrow the throne of Alabasta. They therefore decide to help Princess Vivi to thwart this odious plan. After a stopover in Drum Island where they meet Chopper, our heroes finally arrive in Alabasta. They head to Rainbase, where the despicable instigator Crocodile of Baroque Works resides. Meanwhile, King Cobra, also determined to strike at the source of evil, prepares his troops to head to Rainbase. But at the same time, the rebels deceived by Mr. 2's transformation advance on Alabama. In the meantime, Vivi and her gang rush to Alabama in the hope of preventing the catastrophe, but alas, Crocodile appears and our hero leaps to confront him in a one-on-one battle! Unable to land a single blow on the formidable bandit, Luffy succumbs to Crocodile's sand attacks. Meanwhile, as the rebels approach Alabama, Vivi and the rest of the gang manage to lure Mr. 1 & Co, but fail to stop the rebel troops. The confrontation with the royal army erupts. However, Vivi does not lose hope. Zoro and the others will fight with all their might to help her.
