BROKER is about an unexpected and special journey by people who form a connection through a baby box. Sang-hyun and Dong-soo secretly take an infant from a baby box. However the infant’s mother So- young returns for him, and the three of them set off on an unplanned journey to find the boy new parents. In this way, BROKER captures the process of gradual intimacy and change among people who have each suffered and been hurt in their own way. There is Sang-hyun, who cleverly justifies his action as a benevolent effort to find the baby new parents who will raise him well; Dong-soo, who grew up in an orphanage and knows better than anyone about the pain of being abandoned; and So-young, who left her child at the baby box, but then returned the next day to take him back. Their meeting was unplanned, but in the course of their journey, they form a closeness and share moments of everyday life like any other family.
