When a crew of dirty cops is blackmailed by the Russian mob to execute a virtually impossible heist, they realise the only way to pull it off is to manufacture a 999, police code for "officer down". The chaos that ensues when a police officer is shot in the line of duty is just the diversion they’ll need to do the job, but whether they have the will to kill one of their own is an entirely different matter, triggering a breakneck, action packed finale tangled with double-crosses, greed and revenge.
