Adventure is only limited by imagination in this exciting animated fantasy from The Goonies writer Chris Columbus. Warmly welcomed to the Kingdom of Slumberland by the king himself, young Nemo is christened heir to the throne and given a magical key that will open any door in the kingdom. Though Nemo is warned not to open the one door with the power to destroy Slumberland, temptation proves too strong and the king is kidnapped as a black cloud of nightmares washes over the formerly idyllic dreamscape. Now, if Nemo is to reverse his error and bring the king back alive, he must rally his friends and journey deep into Nightmare Land to face his ultimate fear. Will dreams ever return to Slumberland, or has Nemo's folly set into motion an irreversible, eternal echo of nightmares and chaos?
