In 2003, twenty years after the murder of Mary Fisher, Internal Affairs Officer Sgt. Ian Lynch is assigned to investigate Eric's claim of official misconduct against Russell, now a Lieutenant. Lynch confronts Russell with the allegation, but pressure from the department threatens to derail any chance of a re-investigation. Meanwhile, with the help of a troubled cellmate, Eric discovers a startling piece of overlooked evidence in his legal files.

In the weeks leading up to Mary Fisher's murder, Eric meets Det. Russell for the first time to press charges against Kim Decker, a former girlfriend. Russell suspects the truth is murkier than Eric reported. As Russell investigates the complaint, Eric throws a party at his apartment complex with the help of his older friend and neighbor Trey Carano that quickly spins out of control.
