Soo-Young (SNSD) just moved into her new apartment in the city. However, after a few days of staying in her new apartment, food from her refrigerator started disappearing, and a strange silhouette of a woman started appearing to her during the late hours of the night. Nobody sees it besides her, making everyone think she’s gone completely crazy. Thinking that the apartment was really haunted by a mysterious food-stealing ghost, she seeks the help of The Sherlock Investigation Team (SHINee) to investigate the matter. Was there really a ghost, or it was all just a childish little prank?
