Orphaned then taken in by his gambler uncle, Kim In-ha (Jin Goo) often hangs out with his friends in the basement of a movie theater. He unexpectedly befriends Choi Jung-won, a model student and the rich son of the theater owner. In-ha and Jung-won both fall for Min Su-yeon (Han Ji-min), the daughter of the projectionist at the theater.

But the fire spreads, accidentally killing the gang leader. In-ha is sentenced to seven years, while thanks to his family connections, Jung-won avoids jail time. As In-ha serves his sentence, Jung-won goes to the United States to study and Su-yeon decides to become a nun.
