PART 1: When a child goes to sleep, a magical Door in the Wall appears. Depending on which way the Door's handle is turned, she can choose one of two very different adventures. If turned to the right, she could travel with MollyMalloop. If turned to the left, she could go on an excursion with a frog in a log. But before her adventure really begins, she is startled awake... but is undeterred.

PART 2: Our excited dreamer gets another chance to go through the Door and, with MollyMalloop, she journeys to meet strange creatures and make new friends.

PART 3: After waiting for sometime, the Door reappears and this time she chooses a ride with the top-hatted Frog to Ziggetty Zoo. What grand adventures they have in dreamland, and what fantastical stories she has to share!
