Hye Jung can't remember anything before the age of 4. Every night she experiences terrible nightmares. Unable to cope with the nightmares anymore, she heeds the advice of a shaman and goes back to the villa where her family stayed 24 years ago. The villa is now known as "Wonderland." There, she meets Hwan, Soo Ryeon and a white rabbit. During the next 15 days, Hye-Joong has to find something that is missing. If she succeeds, her nightmares will stop.
