A priceless relic is stolen from identical royals Queen Margaret and Princess Stacy, who enlist the help of their sketchy look-alike cousin Fiona Pembroke to retrieve it.

In the not-too-distant future: after a global catastrophe has wiped out nearly all of humanity on Earth, an elite astronaut from Space Colony Kepler must make a decision that will seal the fate of the people on both planets.

A young orphan boy Jim Button, his best friend Luke and a magical steam engine called Emma travel across the world in search of the truth about where Jim came from. Battling pirates and dragons, outsmarting make-believe giants, they must travel through the Forest of a Thousand Wonders, beyond the End of the World to find the hidden Dragon City.

A year has gone by since Jim Button and his best friend, the engine driver Luke, returned from their dangerous adventure in Dragon City. Life on Morrowland goes its leisurely way again. Suddenly, dark clouds are gathering over the tranquil island of Morrowland: the notorious pirate gang "The Wild 13" has learned that the dragon Mrs Grindtooth has been conquered by Jim and Luke and now swears revenge. To protect Morrowland from another threat, the two of them set off with their steam engines Emma and Molly on a dangerous journey where they meet old friends like princess Li Si, Mr. Tur Tur and Nepomuk and make new friends with Sursulapichi, a real mermaid. On their adventure, Jim's most fervent wish might also come true: to find out the truth about his mysterious origins.
