Like butt play: it isn't as fun as you'd hoped and it stinks. Henry Thomas wastes a movie crawling deep inside the cramped cavity of a house with the catch phrase "I'm just a plumber." This thriller about a man who has to fight off the bad guys from a crawlspace is perfect for plumbers: The acting is what clogs toilets, the action is for drips and the plot has more holes than a leaky pipe.
