Written and directed by Hirokazu Koreeda, this Korean drama follows the story of Sang-hyeon (Song Kang-ho), a small laundry shop owner who also runs an illegal adoption business with his friend Dong-soo (Dong-won Gang). Since Dong-soo works in a nearby church, they steal babies placed in the church's baby box and sell them on the black market. But they are surprised one day when a mother of a nearly-abandoned baby returns and tags along, as she wants to see if the adoptive parents are worth it. The drama co-stars Bae Doona and Ji-eun Lee.
