Zora Matthews, whose mother Sarah conceived her with the aid of an anonymous sperm donor, discovers that her father is a white man named Hal Jackson. This comes as a major shock to Sarah, who had explicitly requested a black donor. On top of that, Jackson is a loud, self-promoting car salesman, which clashes with Sarah's intellectualism. The film revolves around Zora and her mother's rocky relationship with Jackson. Jackson eventually comes to love his daughter and her mother.
