As a rookie member of an elite special-forces team, Rama (Iko Uwais) is instructed to hang back during a covert mission involving the extraction of a brutal crime lord from a rundown fifteen-story apartment block. But when a spotter blows their cover, boss Tama (Ray Sahetaphy) offers lifelong sanctuary to every killer, gangster and thief in the building in exchange for their heads. Now Rama must stand in for the team's fallen leader Jaka (Joe Taslim) and use every bit of his fighting strength - winding through every floor and room to complete the mission and escape with his life.
