Sidney Poitier makes a riveting return to his "In the Heat of the Night" role, as Virgil Tibbs─now with the San Francisco PD─who is assigned to look into the murder of a prostitute. Complicating matters is that the victim was last seen with an old friend, an activist minister (Martin Landau) running for local office. Compelling crime drama co-stars Barbara McNair, Ed Asner, Anthony Zerbe, Jeff Corey; music by Quincy Jones. 108 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital mono; theatrical trailers.
