Plot:
Detective Burke and his men barge into drug dealer George Freemont's house to kill him and destroy all evidence that links them to Freemont's operations. Detective Shaw returns to active duty after the death of his partner. When he uncovers the evidence which is a USB card linking his fellow officers to Freemont's murder, they frame him for a homicide he didn't commit and trap him in the precinct in order to kill him and destroy the evidence that incriminates them. With the cell phone networks and phone lines taken down, Shaw has only 12 rounds left in his gun and intends to make good use of it while trying to expose Burke and his accomplices. Shaw constantly tries to contact Captain Matthews to convince her that he is innocent and that Burke is a dirty cop. He manages to take out all of Burke's crew one by one. Finally down to Shaw and Burke, Burke manages to destroy the USB that contains the evidence and almost kills Shaw, but the power is shut off as the SWAT team enter the building, giving Shaw the opportunity to escape from Burke's clutches. Captain Matthews finally meets Shaw and reveals herself to be a part of Burke's crew for cleaning up all his crimes. But Burke uses this opportunity to kill her right before the SWAT team comes in with Police Chief Keppler. Right when they were going to arrest Shaw, he plays an audio recording of Burke's confession from his phone right after he killed captain Matthews. Burke tries to get a shot off at Shaw but ends up getting shot in the knee instead with the last round from Shaw's gun. Shaw handcuffs Burke and walks out of the precinct.
