This downbeat "noir" thriller raised a few eyebrows due to its violence and controversial themes. Cornel Wilde plays Lt. Leonard Diamond, a dedicated cop─out to bring down crime boss Mr. Brown (Richard Conte)─who gets involved with an icy blonde (Jean Wallace), who happens to be Brown's mistress. Diamond must immerse himself in the Mafia underworld and deal with hit men and seedy informants to take Brown down. Brian Donlevy, Lee Van Cleef, and Earl Holliman co-star. 87 min. Widescreen; Soundtrack: English.
