Derailed

Jin-il (Choi Min-ho) and Ga-young (Da-Eun) are teen runaways who live with other runaway teenagers like a family and work part-time jobs. Sometimes, they steal to survive for the day.

When they run out of money, they make Ga-young lure a middle-aged man Hyung-suk (Ma Dong-seok), to a motel.
