A view into Luffy's past is shown as we are introduced to his hero, the man who gave him the straw hat, Shanks. Shanks and his crew stand up to a group of bandits in the town as young Luffy is taken by the bandits' leader and thrown into the water, where he cannot swim due to his Devil Fruit.
The episode opens with three pirates from Buggy's crew that come upon Nami stranded in a boat. She asks them to save her, but when they climb onto her boat for her treasure she steals their ship, leaving them stranded in the ocean. Meanwhile, Luffy and Zoro are hanging in their boat, drifting at sea, and both of them wonder why they don't have any navigating skills. Suddenly, however, the boat is rocked and Luffy's straw hat blows off of his head, fluttering around through the air. Luffy frantically reaches for it, and Zoro catches it before it lands in the water. This begins a flashback showing Luffy's past.
