Thirteen years ago, a man was convicted for murdering two people at a convenience store. Now Patrick Debreno, Kevin Debreno's brother who's a priest, has to help save him from the death penalty. Someone confessed to him the location of the murder weapon, and Chief Mannion and his team get the suspect and try to make him confess since Patrick can't accuse him. Unfortunately, Gilbert Isaacs is wrongfully killed for a crime he did not commit. The actual murderer, however, storms out of the interrogation room and shoots himself at home. 

Meanwhile, Ella receives a letter from Pablito, Ricky's father. He's asking to see his son, and after a lot of thinking, Ella meets with him and decides not to let Ricky see his father. She still has to convince Ricky that his father being in prison is not his fault.

The gangster wars have crossed the limits, leaving a bloody trail and numerous victims. Mannion has Temple working undercovered, trying to reach the big boss on the drug dealing schemes. But it's not such an easy road, forcing Temple to try some crack to prove he's not a cop. That brings back ghosts from his druggie past, which Temple may not be strong enough to fight again. Meanwhile, Mannion himself interferes with the gangsters, interrogating young 12-year-old Junior about homicides. Later, Parras and Brander are victims of an ambush and kidnapped by the gangsters. Luckily the police force rescues them before anything happens. Mannion sees no way out but to turn to Richard Gray for help. With him, he gets the gang leaders to settle a non-aggression deal. When everything seems to be going back to its place, Temple looks for drug dealers to buy some crack. Ella turns down Clive's proposal to move to Seattle with him, and he decides to stay and marry her. And Mannion's life is threatened.
