Ken Park focuses on several teenagers and their tormented home lives. Shawn seems to be the most conventional. Tate is brimming with psychotic rage; Claude is habitually harassed by his brutish father and coddled, rather uncomfortably, by his enormously pregnant mother. Peaches looks after her devoutly religious father but yearns for freedom. They're all rather tight, or so they claim. But they spend precious little time together and none of them seems to know much about one another's family lives. This bizarre dichotomy underscores their alienation, the result of suburban ennui, a teenager's inherent sense of melodrama, and the disturbing nature of their home environments.

Young widow Anna is finally getting on with her life after her husband Sean's death. Now engaged to be married, she meets a 10-year-old boy who tells her he is Sean reincarnated. Though his story is both unsettling and absurd, Anna can't get the boy out of her mind. And much to her fiancé's concern, her increased contact with him leads her to question the choices she has made in her life.
