Six friends sneak into a forgotten Cold War bunker, now a clandestine nightclub carved into the earth, where the bass drops into pure darkness. When the door slams shut behind them, they realize the walls aren’t just concrete—they’re crawling with something that was once human. With only flickering lights and a dying phone, every corridor leads to the same screeching whisper. The mutated dwellers don’t just hunt; they play, toying with their prey before the lights go out. One by one, the friends must outwit the creatures and find a way back to the surface before they become permanent residents of this underground hell.
