Doraemon: Nobita's Treasure Island

Upon hearing about the story of Treasure Island, Nobita dreams of discovering and exploring his own treasure island, despite the fact all of the Earth has been mapped already. Doraemon provides Nobita a special treasure map that shows him the location of a treasure island. At the same time, the media announces the discovery of a completely unknown island. Believing the new island is the treasure island, Nobita and Doraemon recruits Shizuka to accompany them, with Doraemon providing a ship. Gian and Suneo also tag along.

However, as they get near the island, they are suddenly attacked by a gang of pirates. At that moment, the island begins to move, revealing that it is a part of a massive advanced technological ship. The pirates retreat, but abduct Shizuka in the process. Nobita and his friends are unable to rescue her, but save an unconscious boy named Flock. Flock explains that the pirates that attacked them are actually time travelers, who travels to different eras and steal treasures off the sea floor. Flock reveals that he was also part of the ship's crew, but decided to desert since he couldn't accept taking orders from Captain Silver. Doraemon uses the treasure map to track the pirate ship's location.

Meanwhile on the pirate ship, Shizuka encounters Flock's sister Sarah, who looks exactly like Shizuka. Sarah agrees to help Shizuka. Flock and Sarah reveal that Captain Silver is actually their father, who went mad when their mother died and has become obsessed with gathering as much treasure as possible. Nobita and his friends attempt a rescue operation, but end up rescuing picking up Sarah instead of Shizuka, who is taken directly to Captain Silver. Captain Silver moves on the final stage of his plan. Having seen humanity's destruction in the future, Captain Silver is determined to launch his pirate ship into space and colonize a new planet with all of the treasure he has acquired. However, this requires him to drain the Earth's energy to get the power he needs to reach space.

Doraemon warns that taking Earth's energy will result in its destruction. Due to which, Nobita and his friends, along with Flock and Sarah attack the pirate ship again. Gian and Suneo stay behind to occupy the pirates while Nobita, Doraemon, Flock and Sarah confront Captain Silver directly. While Nobita and Doraemon delay the activation of the pirate ship's engine, Flock is able to seize control of the ship and eject the energy back into Earth. Captain Silver realizes his mistakes about neglecting his children and abandons his plans, where he promises to be a better father to them. Afterwards, Flock, Sarah, Captain Silver and the rest of the crew return to their own time while Nobita and his friends return home with Nobita gaining a new appreciation for his own father Nobisuke.
