This raucous comedy tracks two parallel parties as they -- and their guests -- unravel throughout the evening. The first bash begins when Scott's (Scott Speedman) parents head out for the night, to be replaced quickly by Scott's brash, rash friends bent on having a grand old time at all costs. While things quickly go downhill there, his parents aren't enjoying their soiree, either. With the drinks flowing freely, conflict floats to the surface.
