London cop Tom Brant (Jason Statham) is unlikely teamed with his new gay boss Sgt. Porter Nash who's battling homophobia from within the force. Brant is on the track of a vicious cop-killer who calls himself 'Blitz'. With their prime suspect narrowed down to the seriously unhinged Weiss (Aidan Gillen) who demands to update his Facebook before he sees his lawyer, they lack sufficient evidence to charge him. Weiss is released and police continue to die. No matter the rules, no matter the method, Brant must hunt him down and stop him before he himself becomes the city's next dead cop!
