Big Town

Big Town is a government green facility that invites obese people to lose all of their unwanted pounds in a week's time; painlessly and effortlessly, and at no cost to them. Rose and Bruno, an overweight couple, answer the ad and discover that their energy creates electricity. Their fat is converted into an alternative bio-fuel while they sleep; but, things go wrong: people die, and three robots do a cover-up on their own.
