One night in the pouring rain, they secretly carry off an infant who was left at the baby box. But on the following day, the mother So-young (LEE Ji Eun) unexpectedly returns for her son Woo-sung. Realizing that her baby has been taken, she is about to call the police when the two men tell her everything. Their claim that they stole the baby in order to find him a good home seems outrageous, but So-young ends up joining Sang-hyun and Dong-soo on a journey to find new parents for Woo-sung.
Meanwhile, the police detective Su-jin (Doona BAE) and her younger colleague Detective Lee (LEE Joo Young) are witnessing all of this as it unfolds. They silently tail the group, hoping to catch them in the act at all costs to wrap up their half-year investigation.
Brought together by chance through a baby box, the five individuals embark on an unusual and unexpected journey.
