Rookie cop Rama (Iko Uwais) is part of an ill-prepared SWAT team charged with infiltrating a 15-storey apartment block, which doubles as the headquarters of notorious drug lord Tama (Ray Sahetapy) and his sadistic henchmen.

The cops have one simple and admittedly difficult objective: fight their way to the top floor and destroy Tama's criminal network.

The good guys quickly realise they have stumbled into a trap.

Over a loudspeaker, Tama offers residents of the block a princely sum to slay the cops outside their front doors.
