The hunt is on for a serial killer in San Francisco. Few cases in the history of true crime are as intriguing as that of Zodiac, a bizarre gunman in an executioner's hood, who taunts the police with dozens of letters containing eerie messages and cryptograms. Director David Fincher (Panic Room, Fight Club, Se7en) captures the story of the infamous killer who terrorized the city in the late 1960s. Jake Gyllenhaal (Jarhead, The Day After Tomorrow), Robert Downey, Jr. (Kiss Kiss, Bang Bang), Anthony Edwards ("ER") and Mark Ruffalo (We Don't Live Here Anymore, Rumor Has It...) star.
