"Working late-night surveillance at a luxury condominium development in a city world famous for corruption, Chicago private detective Joe Kozmarski encounters a burglary crew. Two of the crew members show up in a police cruiser. In the chaos that follows, Kozmarski shoots and kills a thief, who is also one of Chicago's finest. Kozmarski is in for many a bad night's sleep. He joins the criminal crew, working as an inside agent for his old friend Lieutenant Bill Gubman. Facing dangerous suspicions from both the criminal gang and the uncorrupted ranks of the police department, uncertain who wishes him to stay alive and who wishes him dead, Kozmarski takes a wild, dangerous ride. In the high-end Spa Club, during a showdown with a consortium of Chicago street gangs, and in a breakneck rooftop chase, "A Bad Night's Sleep" pushes full throttle to a stunning conclusion.
