The body of a young woman is found in a dumpster in Chicago and detectives Andy Polanski and Frank Campello are charged with finding the killer. The two are polar opposites. Polanski is the son of a disgraced Chicago police officer and is fastidious about his reputation. He has also recently been transferred from another district having blown the whistle on some corrupt cops. Campello, however, takes a live and let live approach to his life and job.
