Hye-Joong (Jung So Min) can not remember anything before the age of 4 years. Every night he's always terrible nightmare. He then went to the villa where the family lived 24 years ago, although it was banned by a shaman. Villa is now known as the "Wonderland." There, he met Hwan (Hong Jong-Hyun), Soo-Ryun (Jung Yeon-Joo) and a white rabbit. During the next 15 days, Hye-Joong had to find something missing. If he succeeds nightmares will stop.
