Tom is a fourteen-year-old boy living with his adopted grandmother when he receives a letter from a law firm inviting him to the reading of a will. It's the will of his great-uncle, Heinrich, his grandmother's brother. He's just absorbing that information when there's a knock at the door. The man at the door is his Uncle Welf.
It's worth noting that Tom had never heard of Great-Uncle Heinrich or Uncle Welf before.
Uncle Welf drives them to the reading of the will, where Tom learns that he will inherit more than ten million euros if he takes control of Heinrich's ghost train carnival ride, the Terror Train, and keeps it operating until he's eighteen. Uncle Welf, of course, will be his agent because he's underage, but he'll have to travel with the ride.
