Mute Hee-Jin is working as a clerk in a fishing resort in the Korean wilderness; selling baits, food and occasionally her body to the fishing tourists. One day she falls in love with Hyun-Shik, who is on the run from the police, and rescues him with a fish hook when he tries to commit suicide.

Jin-a, a young prostitute, moves into a seaside motel called the Birdcage Inn, run by a dysfunctional family. Struggling with her circumstances and the family's treatment, she forms an unlikely bond with the daughter, Hye-mi. As they navigate love, betrayal, and personal growth, their friendship ultimately leads to a deeper understanding and a chance for redemption.
