GASCAR is the inspirational tale of Amos Wallace, a talented NASCAR driver who has completely lost his passion for the sport. After his sponsors drop him, Amos turns to the shady all-natural juice company NutriQuaff and, during a routine race, he feels the obvious side effects of ingesting six bottles of the product. By envisioning the toilet as his finish line and incorporating the juice into his routine, Amos is almost guaranteed first place. But with his constant success, it seems his competition isn't willing to put up with his crap anymore.
