Self-proclaimed tough guy Jae-pil (played by LEE SUNG MIN) and sexy guy Sang-gu (played by LEE HEE JUN) leave an unforgettable first impression on their moving day. Despite becoming special surveillance targets for Police Chief Choi (played by PARK JI HWAN) and Officer Nam (played by LEE KYOO HYUNG), they are simply happy to start anew in their European-style dream house. However, happiness is short-lived as they are inadvertently mistaken for kidnappers while trying to rescue Mina (played by GONG SEUNG YEON), who almost drowns. Meanwhile, uninvited guests looking for Mina start appearing, and an ancient spirit sealed in the basement awakens, surrounding the house with dark energy.
