The Steel Jungle is the prison where most of this film takes place. Perry Lopez heads the cast as two-bit bookie Ed Novak, who goes to jail rather than squeal on his Syndicate higher-ups. Novak's silence exacts a toll on his wife Frances (Beverly Garland), who is expecting a child. The longer he remains in prison, the more Novak becomes aware that the mob has deserted him--and the more he's willing to spill what he knows. Fellow prisoner Steve Marlin (Ted De Corsia) intends to see that Novak keeps his mouth shut permananently. Produced independently, The Steel Jungle was distributed by Warner Bros.
