Young Jim Hawkins, accompanied by his mother, is running the Benbow Inn with her when he meets Captain Billy Bones. The captain has been killed while the inn was besieged by a group of buccaneers led by Blind Pew. In a moment of bravery, Jim and his mother fight off the attackers and discover the treasure map that leads to the treasure hidden on a mysterious island.
Jim agrees to sail on the Hispaniola with Squire Trelawney and Dr. Livesey to find the treasure on that island. Upon arrival, the ship's cook and troublemaker, Long John Silver, leads a mutiny among the crew members who want to claim the treasure for themselves.
Jim helps the Squire and the Hispaniola officers survive the mutiny and fight back against Silver's men, who have taken over the ship. After a fierce battle, they manage to reclaim the Hispaniola and continue their journey to the island.
On the island, they discover that the treasure is hidden deep within a cave. However, they soon realize that the cave is guarded by a powerful dragon. Jim and his companions must work together to overcome this challenge and retrieve the treasure.
With the help of their newfound allies, the group successfully defeats the dragon and uncovers the treasure. They return home with the riches they discovered, grateful for their adventure and the bonds they formed along the way.
