In the dingy port town of Incheon, five friends attempt to make the difficult transition from high school to the adult world: Hae-joo, who is pursuing a career at a brokerage firm in Seoul; Tae-hee, who works for free at her family's sauna and volunteers as a typist for a poet suffering from cerebral palsy; Ji-young, an artist who lives in the slums with her elderly grandparents; and half Chinese twins Bi-ryu and Ohn-jo, who make their living selling handmade jewellery on the street.
