'One afternoon twins Devine and David take their grandma's dog for a walk to a new Fantasy Park. Inside the park they find a strange and constantly changing world. They meet many odd characters; some are helpful and some are unpleasant. The only way out of the park is through doors magically guarded by the Doorman. In order to get through each door the twins have to successfully answer riddles he asks. The twins find that being in the park is not always pleasant and getting out of it is definitely not easy.'
