Jules Dassin's opens with cheap grifter Harry Fabian (Richard Widmark) running for his life through the streets of London. Harry wants to be big-time, and he does not care how he raises cash for his schemes. Like a junkie, he uses and steals from his girlfriend Mary (Gene Tierney), a singer at the Silver Fox, a seedy nightclub owned by the physically grotesque Phil Nosseross Francis L. Sullivan. Harry, who also works for Phil steering unsuspecting customers to the club, comes up with a plan to wrest control of professional wrestling from promoter and underworld kingpin Kristo (Herbert Lom) by manipulating Kristo through his father, retired wrestling great Gregorius (Stanislaus Zbyszko). For financial backing, Harry turns to Phil and Phil's wife Helen Googie Withers, both of whom give him the money, but only to further their own ends. When Gregorius is accidentally killed by his protege's upcoming opponent, Strangler (Mike Mazurki), and Phil realizes that Helen is leaving him for Harry, the scheme quickly unravels. Truly a glimpse of hell, 's distorted visuals and dark symbolism depict an underworld from which there is no escape and in which redemption comes at a very high price.
