Inside Detroit (1956)

Gus Linden (Pat O'Brien) former racketeer head of a Detroit local of the United Automobile Workers of America, A.F.L, attempts to destroy his successor, Blair Vickers (Dennis O'Keefe), so he can put his old rackets back into the auto factories. Vickers fights him off, ultimately winning help from Linden's attractive daughter, Barbara (Margaret Field), and from Joni Calvin (Tina Carver), Linden's moll.
