Nothing is more important to Mexican-American Marta Delacruz than her quinceanera -- the traditional 15th birthday celebration that symbolically ushers a young girl into adulthood. Marta is understandably angry and resentful when her father cancels the gala event, but her outlook changes completely when she accidentally uncovers her father's secret: He never became a U.S. citizen.

Based on the true story of Richard "The Night Stalker" Ramirez who terrorized California in 1985 and the two Los Angeles police detectives who try to track him down.
