The village of Wall nestles alongside a mysterious wall that must not be crossed. But when Tristan promises to bring his beloved Victoria a star that has fallen on the other side of the divide, he finds himself caught up in a mystical world.
Four treacherous sons also seek the star to gain their dying father's throne, as do three evil witches. When the star takes the human form of Yvaine, Tristan sets out to take her to Victoria and must face deadly enemies as well as unlikely allies in Matthew Vaughn's delightful family fantasy.
