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.

Twenty years after Mary Fisher's death, Internal Affairs Sgt. Lynch and Det. Chen fly to Texas to interview Trey Carano, a former friend of Eric's, who shares his account of Eric's whereabouts in the days and hours leading up to the murder.
