 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 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, convincing Mac to rob the restaurant s safe and then murder Norm, using the robbery as a way of throwing 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 there s foul play at the new center of the fast food universe, and when the McBeths fear that fry cook Banco knows more than he s letting on, Mac takes charge in the plotting department and decides there may be more dead meat on the menu.
