The Circle Line

Officer Lewis Powell fell off the wagon and woke up in an alley covered in blood with his off duty weapon missing. He tells Walsh he may have killed someone the night before during an alcohol-induced blackout and asks for his help. While Walsh and Shraeger scramble to put together the pieces of Lewis' missing night, Banks and Delahoy learn they are both victims of identity theft. When they investigate the murder of the man pretending to be Banks, Delahoy and Banks get a glimpse into the lives of the men who've stolen their identities and consider changing the way they live.
