Scotland, PA

Joe McBeth is a hard-working but unambitious doofus who toils at a hamburger stand alongside his wife Pat, who has a significant edge in the brains department. Pat is convinced that she could do a lot better with the place than their boss Norm Duncan is doing, so she works up a plan to usurp Norm and convinces Mac to rob the restaurant's safe and murder Norm, using the robbery to throw the police off their trail. Though two stoners and a would-be fortune teller warn Mac that bad luck awaits him, he gathers his courage and goes through with his wife's scheme. At first, things seem to have gone just as Pat hoped, and after Norm's sons sell the restaurant to the McBeths (they pay for it with the money they stole from Norm), business takes off. But vegetarian police detective McDuff is convinced that there's foul play at the new center of the fast food universe, and when the McBeths fear that fry cook Banko knows more than he's telling, Mac takes charge of plotting and decides that more dead meat could be on the menu.
