S01E18 — Night Moves

Mannion decides to declare war against street gangs after a drive by shooting kills an innocent pedestrian. Two Latino gangs (the "Colombian Guardian Crew" - C.G.C. - and "Los Muertos") - one Cuban and one Salvadorian - are in war with each other over territory limits and Mannion sends his best men to catch the main leader accused of killing the pedestrian: Carlos "El Gato" Cesar, one of the most dangerous gang members in the city. Meanwhile, Mannion has suspicions that the same man that reported a criminal fire is the one who started it; and Nick has to face his fears after being badly beaten up by a robber.
