They end up telling Scanlon he must remain locked up until after the next election, angering the gangster, who threatens to tell all. Welsh and Turk make a phone call to Scanlon's unseen mob boss for instructions. McQuigg has the gun that killed Johnson, which has Scanlon's fingerprints on it. McQuigg ignores the gangster's lawyer, ripping up his writ of habeas corpus. At the police precinct one night, Scanlon walks in alone demanding to see Irene, who is being held in protective custody, and kills Johnson in cold blood. Honest cop Bob Johnson is helpful to McQuigg, as is reporter Dave Ames, who has a romantic interest in Irene. A bomb explodes near McQuigg's home, frightening his wife, Mary. McQuigg not only wants to nail Scanlon, but also stop all the mob corruption in the city вЂ“- without getting himself or his witness killed. McQuigg persuades sexy nightclub singer Irene Hayes to testify against Scanlon, which marks her for death. The city's prosecuting attorney, Welsh, and a state police detective, Turk, are crooked and make McQuigg's job as an honest officer nearly impossible. However, he can't seem to touch the incorruptible police captain Tom McQuigg, who refuses all attempts at bribery. Racketeer and mobster Nick Scanlon has managed to buy several of the local government and law-enforcement officials of a large midwestern American city. The plot is very close to the original play and the 1928 movie.
