Deep beneath the neon glow of a bustling metropolis lies a forgotten network of tunnels – the remnants of an abandoned subway line. Maya, a fearless urban explorer, leads her crew – Ben (the tech wiz), Sarah (the cautious one), and Alex (the joker) – on a daring expedition. Equipped with headlamps, cameras, and a thirst for adrenaline, they descend into the darkness. Little do they know, they've awakened a slumbering entity guarding a long-buried secret. Trapped and hunted in the claustrophobic tunnels, they must fight for survival in a desperate race against time.
