A modern take on Shakespeare's "Macbeth" set in a 1970s Pennsylvania diner. Mac and Pat McBeth are stuck in their dead-end jobs at Duncan's Restaurant. Restless and a bit delusional, they hear about the boss's idea for revolutionizing the fast-food industry and hatch a plan that will solve all their woes. As events unfold, it seems the happy couple has attained the American Dream of fame, fortune, and french fries. However, as bodies start dropping, Mac begins to break down further, and Pat becomes more than a little obsessed with a nasty burn "spot" on her hand. These incidents arouse the suspicions of co-worker, Anthony "Banko" Banconi and police lieutenant Ernie McDuff.
