Sang-hyeon runs a laundromat and helps out at the church where his pal Dong-soo serves as a volunteer. Sang-hyeon and Dong-soo conduct an illegal business together: on occasion, Sang-hyeon will kidnap newborns from the church's baby box, with the help of Dong-soo, who will delete the church's CCTV tape showing a baby was put there, and then they will sell the babies on the adoption black market. So-young, a young mother who had previously abandoned her baby, eventually finds them and decides to accompany them on their road trip to meet the kid's future infertile parents. Meanwhile, Soo-jin and Detective Lee of the police department are hot on their trail.
