Thomas & Friends: Sodor's Legend of the Lost Treasure

Thomas the Tank Engine takes an opportunity to beat Bertie the Bus in a race on his branch line When Bertie gets stuck behind an excavator on the road. Bertie complains about all of the machines working on the new branch line, which concerns Thomas' coaches Annie and Clarabel. The next morning, Thomas gets too silly and causes an accident at Knapford Junction with the express coaches. Sir Topham Hatt sends Thomas to the construction yard to work on the new branch line by force, while the new engine, Ryan, is given Thomas' job for the time being.

At the building site, part of the land subsides underneath the new track. When Thomas arrives, he does not pay attention to the danger signs, falls into a cavern, and finds a pirate ship. While being lifted out, he tries to tell Sir Topham Hatt about the pirate ship, but he refuses to listen. The ship is found again by Rocky, and put onto display at Arlesburgh Harbour. After being repaired, Thomas meets Sailor John and his boat Skiff, which has been fitted with wheels that allow him to move on the rails. Sailor John explains that he is looking for treasure, but is hesitant to give Thomas any details.

Shortly after Thomas saves Ryan from dynamites, a furious Sir Topham Hatt wrongfully rages at Thomas for causing disasters at the construction yard, refuses to listen again and sends him back to his shed in disgrace to have him stay there until further notice while ordering everybody else to get back to work. As Marion is digging into the side of a cliff in preparation for the rerouted track, she finds a treasure chest full of gold and jewelry. The Fat Controller decides to donate it to a museum. Thomas meets up with Sailor John on his way back to Knapford, who reveals that the treasure Marion had found is the same one he had been looking for, and angrily demands for it to be given to him. Thomas says that Sir Topham Hatt has the treasure, and refuses to help Sailor John take it.

That night, Sailor John breaks into Sir Topham Hatt’s office and steals the treasure chest, using Skiff as his reluctant getaway. Thomas chases them down the line and sees that Sailor John has rigged Skiff to the pirate ship on wheels, speeding down a hill. The chase goes through Arlesdale Junction where the miniature engines slow down the ship by knocking their ballast trucks over the rails. A loose rope attached to the ship gets stuck on Ryan, derailing it and leaving Sailor John with only Skiff to take him away.

At Arlesburgh Harbour, Thomas tries to knock Skiff off of the rails, but to no avail. They all end up at the rail-boat launch ramp where Sailor John rows skiff out towards the sea, and Thomas ends up partially submerged under water. With the help of a large wave, Skiff knocks Sailor John and the treasure off of him. The treasure sinks to the bottom of the harbour, and Sailor John is arrested by the police.

When the branch line is finished, Sir Topham Hatt gives Thomas his old job back, and lets him cut the ribbon to the new line; meanwhile, Skiff now gives railboat tours around Arlesburgh Harbour.
