When a midnight scavenger hunt for a rare bud of weed brings a group of party-hungry stoners to a haunted hotel, they open a portal and unleash a group of ghastly hysterical creatures that has only one mission: party ‘till you die.

A group of friends get lost in the seedy streets where they encounter a crazed gang of homeless derelicts that seizes them and kills them one by one. The surviving man escapes on foot, naked and unarmed, with a pack of depraved transients in pursuit, and only seconds away from capture.
