A university student finds himself wrapped up in the bizarre world of his next door neighbor, learning about his history and relationship with a girl who changed his life.

Seconds before Reika (from the first movie) dies, she gives the key to a coin locker to her pupil Ayano. After a hunt for the right coin locker, Ayano finally finds the right one but she soon realizes that some things should be left alone. When some other students at her school finds the coin locker, the curse begins once again. The long haired girl is once again out to get anyone who’s opened the coin locker.

A child abandoned in a subway coin locker is sold to a ruthless and calculating loan shark and gangster boss dubbed “Mother” (Kim Hye-soo), who runs an organ-harvesting ring in Incheon’s Chinatown. Named Il-Young (Kim Go-Eun), the baby girl grows into Mother’s loyal right-hand enforcer and is groomed to be her eventual successor. But when Il-Young’s loyalty to Mother wavers, the clash between the two unleashes a merciless tidal wave of blood-soaked retribution and strife.
