Chaos erupts as a swarm of monstrous, genetically altered spiders descend on a crumbling city. Trapped beneath the surface in a collapsing tunnel, two strangers - wounded, disoriented, and running out of time - must work together to escape. With every step deeper into the dark, the walls close in and the threat grows deadlier. Hunted by the relentless creatures skittering through the shadows, survival means facing their worst fears... or becoming prey.
