I Came from Busan (2009)

Eighteen-year-old In-hwa lives alone in Busan. Nobody knows she is pregnant, except her closest friend Sang-mi, who persuades her to put the baby up for adoption. In-hwa reluctantly abandons the infant. As time goes by, her yearning for the baby grows stronger and she visits the adoption agency to ask if she get the child back. The staff reject her request, arguing that the baby will be much better off with her new family. Knowing the adoptive family's address in France, In-hwa decides to take a trip.
