A gang gun battle in front of a church and a rash of car thefts leads Manion and team to suspect the carjackers are part of an organized and growing El Salvadoran ring that's transporting the cars to El Salvador for sale. Using RICO statutes to begin rounding up suspects for questioning, the gang retaliates by targeting Manion's Gang Task Force commander. In a shootout, Dept. Chief Nolan is seriously wounded.
