When the LAPD kills several members of the South Central gang Street Thunder, the remaining members avenge themselves by way of a bloody war waged against cops and citizens alike. Caught in the crossfire is Lt. Ethan Bishop (Austin Stoker), who's managing a skeleton crew at the local and soon-to-be-closed police precinct. As the gang members close in, Bishop forms an unlikely alliance with a group of prisoners in order to defend the station and the lives of everyone in it.
