Mu-jin is severely injured while working as a day labourer at a construction site. Meanwhile, his older sister, Yoon-jin, confronts Gyu-rim and urges her to end her relationship with Mu-jin. At the same time, Gyu-rim’s family is evicted from their home. Eight years later, Gyu-rim lives with her young son, Gyeol. However, she is summoned to the police station, where she comes face to face with someone she never expected to see again.
