In Anderson, California, where ethnic minorities gather, six gang members were killed by police in the early hours of a Saturday morning. Their accomplices swore to avenge them. In the afternoon of the same day, Lieutenant Bishop (Austin Stoker) is assigned to guard a soon-to-be-abandoned police station, while three criminals, led by the ferocious criminal Napoleon Wilson (Darwin Joston), will be escorted to another prison at Rocklosses Prison in California. The vengeful gang shot and killed a little girl at random on the road. The girl's father killed a gangster and then fled to the police station guarded by Bishop, where there were only Bishop and two female clerks. in addition, the escort car was transferred to this police station not long ago because of the prisoner's emergency on the way. At this time, police officers and prisoners were ambushed and shot by gang members outside, and Bishop decided to use Wilson's power to resist the thugs outside the police station.
