Scotland, PA is a blackly comedic retelling of Shakespeare's 'Macbeth', set against the backdrop of a fast food restaurant in early 70's, rural Pennsylvania. This classic tale of guilt and betrayal centres on the McBeths, Joe "Mac" and Pat, who are stuck in their dead end jobs at Duncan's Restaurant. While their boss, Norm Duncan, a visionary, dreams of turning his restaurant into a Fast Food empire Pat McBeth hatches a plan. When Norm meets with a bizarre death, Lieutenant Ernie McDuff is called in to investigate. Things seem to work out well for "Mac" and Pat after Malcolm and Donald sell the restaurant to their father's favourite employees. The McBeths transform Duncan's Restaurant into the wildly successful, state-of-the-art, fast food mecca called McBeth's Restaurant and life is good for the McBeths. That is, until "Mac's" friend and co-worker Anthony "Banko" Banconi, starts becoming suspicious as people begin to disappear. With McDuff hot on the trail, the McBeths' dream of fame, fortune and french fries crumbles before their eyes.
