Old and decrepit Krank has lost his capacity for dreaming and is attempting to fight death by stealing the dreams of children. Krank's cadre of cloned henchmen snatch 5-year-old Denree to subject him to the horrific dream-retrieval process. The boy's father, One, the hulking strongman of a traveling circus, and his precocious 9-year-old friend, Miette, join forces to defeat Krank's minions and save Denree.
