A young girl teams up with a hatchet-wielding teddy bear to solve the mystery of her mother's murder and get her revenge in this campy slasher from Cho Yeeun, a rising star in Korean horror.

Hwa-young never believed that her mother was murdered in a mass-cyanide attack at the luxury apartment complex where she worked. Now living in a flophouse for runaway teens, she is determined to save 20 million won to put a hit out on the suspect and engages in any odd jobs she can find. 

When her unscrupulous landlord convinces her to be bait for one of his electronics scams, Hwa-young finds herself trapped in a seedy motel with a strange man. Realizing her life is in danger, Hwa-young tries to escape but finds herself overpowered until an unlikely hero saves her. A hatchet-wielding Happy Smile bear.

Hwa-young and teddy bear, who is possessed by the spirit of a murdered boy, team up for a revenge quest unlike any other.
