Deep in the heart of Jakarta's slums lies an impenetrable derelict apartment building which became a safe house for the world's most dangerous killers and gangsters. The rundown apartment block has been considered untouchable to even the bravest of police. Cloaked under the cover of pre-dawn darkness and silence, an elite team is tasked with raiding the derelict apartment in order to take down the notorious drug lord that runs it. But when a chance encounter with a spotter blows their cover and news of their assault reaches the drug lord, the building's lights are cut off and all exits are blocked. Stranded on the 6th floor with no way out, the unit must fight their way through the city's worst criminals to survive their mission.
