Scotland, PA

Joe and Pat McBeth (James LeGros and Maura Tierney) reach success by killing their fast food boss Norm Duncan (James Rebhorn), rennovating the burger stand to include a drive thru window, and renaming it as McBeths. Things begin to unravel with the arrival of a vegetarian detective named McDuff (Christopher Walken). The three stoned hippies tell Joe McBeth to murder McDuff but he fails, and falls to his death upon the bull-horn ornaments on his Camaro.
Thanks, Don P!

This movie was based on Shakespeare's Macbeth, which was also used as the basis for the movie Throne of Blood.
