Jong-du, a young man just out of prison for manslaughter, is a social misfit: fidgety, snuffling, laughing inappropriately, without a super ego. When released, he calls on the family of the victim; they send him away, but not before he has seen Gong-ju, a young woman disabled severely by cerebral palsy. Both are abused by their families, and both are used by them as well. Although their relationship begins with Jong-du's criminal behavior, a friendship develops.
