Ray is a young wunderkind inventor living in Victorian England. His life is turned upside down when he receives a special package hailing from the United States, sent by his grandfather, Lloyd Steam. The package contains a device called a Steam Ball, a device so powerful that it can drive any machine that requires steam with a nearly limitless amount of energy. Ray is instructed to not let the Steam Ball fall into the wrong hands, which include the mighty O'Hara Foundation, who desperately want to bring the Steam Ball back into their control so they can achieve their less than noble goals. He will need to use every bit of his brilliance in order to dodge the countless goons that are sent to snatch the device from him. It will be a battle between good and evil, a battle for redemption, a battle for the future!

The film opens with Nefeltari Vivi flying with Pell in a brief flashback. Returning to the present, Vivi and the Straw Hats meet Crocodile's subordinate Mr. 2 Bon Clay. Mr. 2 shows the Straw Hats his devil fruit ability, which allows him to assume the form and voice of anyone whose face he has touched. Vivi describes a brief history on how the Baroque Works leader Crocodile has used Dance Powder while posing as the country's hero. He has also tricked the rebel and royal armies into fighting each other. Once in Alabasta and after crossing the desert, the Straw Hats find the rebel's base deserted, while the rebel army, led by Vivi's childhood friend Koza, witnesses the port town Nanohana being burned by members of Baroque Works disguised as soldiers of the royal army. The rebels decide to attack Alubarna, where at the same time Mr. 2 impersonates the king, Nefeltari Cobra, and orders the royal army to engage. Meanwhile in the desert, the Straw Hats are intercepted by Crocodile and his partner, Ms. All Sunday. Crocodile aims for Vivi, but Luffy stays behind and distracts him, while the other Straw Hats escape. In the ensuing fight, Crocodile defeats Luffy by impaling him through the chest with his hook and buried alive.

Three years have passed since the bombing of Hiroshima and Gen is now a fourth-grader. Hiroshima is still a ruin, and Gen must scrounge for scrap metal to help keep himself and his remaining family fed, but at least commerce has returned to the land. As his mother gradually grows ill from radiation sickness, Gen and Ryuta befriend a group of orphans led by a tough-nosed older child and including a girl who still bears ugly burn scars from the day of the bomb. An old man suffering from depression is also drawn into the group as they come together to support each other and form a makeshift family. Reality is still harsh, however, as many orphans still die lonely deaths and the grim reminders of what happened linger everywhere. (Source: ANN)
