Deep within the heart of Jakarta's slums stands an impenetrable apartment fortress, owned by the ruthless drug lord Tama and serving as a safe house for the city’s most dangerous murderers and gangsters. An elite squad of twenty Indonesian SWAT members, led by the determined Sergeant Jaka and the young rookie Rama, is tasked with a covert, pre-dawn raid to infiltrate the building and capture Tama. Rama, driven by a personal motivation to ensure his family's safety, eagerly participates in the operation, hoping to return to his pregnant wife. As dawn breaks, the team quietly enters the building, undetected at first, but when their cover is blown, Tama offers free rein to all criminals inside: kill the cops and earn permanent free residence.

The botched surprise rapidly devolves into chaos, trapping the outnumbered and outgunned police squad inside the enemy territory. Amid ferocious resistance from Tama's legions, the team's control weakens, leading to a treacherous struggle for survival as they ascend the building's floors. Mercilessly hunted and fighting against all odds, Rama showcases his fierce combat skills while evading death traps and brutal henchmen set on stopping the squad's advance at all costs. Tensions escalate with the realization that betrayal and corruption within their ranks could undermine the operation and cost them their lives, forcing Rama and his remaining allies to trust their instincts and combat prowess to outwit their relentless foes.
