Synopsis: In this major motion picture, Nemo journeys to the Kingdom of Slumberland. The King of Slumberland welcomes Nemo with open arms, making him heir to the throne and giving him a magical key that opens any door in the kingdom. "But I must warn you," the King says, "there is one door you must never open."
Not heeding the King's advice, Nemo unlocks the door. With the King kidnapped and nightmares unleashed upon the kind people of Slumberland, Nemo and his friends must venture into the depths of the Nightmare Land in a courageous attempt to make things right.
