In a high-rise apartment block, tenants must deal with a nightmarish and unusual infestation. Little do they know, their fates would become intertwined. It starts with a bite followed by the sensation of something literally crawling under their skins. The sneezing comes next, the evacuating of a silk-like substance emerging through every orifice. Then comes the tiny black spiders with the small venomous fangs and with a unified, hive-minded purpose. It's soon revealed that the humans are mere vectors for the sole intent of bringing sustenance in the form of human flesh and blood to the brood mother, slowly growing larger and stronger within the building's boiler room. Prepare yourselves for an arachnophobia experience the likes of which will scare you senseless!
