An elite team of security contractors is deployed to rescue a VIP on an exclusive island.
They discover the island devoid of human life: the neighborhoods abandoned, the streets eerily vacant. As they press further into the island, they are confronted by masked gunmen, deadly, unknown technology and an unfamiliar droning sound that is inescapable.
As the threats intensify so does the sound, gaining in volume and deadly side effects. The rescue mission evolves into a desperate attempt to survive, escaping the island and the sinister presence that seeks to harm them.
