Angus and Dorian Montier are two brothers who team up to kill their mother's cheating husband, Henry Lever, by frightening him to death by chasing him with a helpicopter (he has a heart condition). They are successful, but when a fast food returant worker picks up their frequency with her head phones, Dorian (Luke Wilson)goes undercover as a fast food worker to determine whether or not the worker knows the truth. The worker is Sally Jackson, unlucky in love and nine months pregnant with a boy. Sally also happens to be the former mistress of Dorian's cheating stepfather (she didn't know he was married) and the mother of Henry Lever's unborn child and Dorian is falling in love with her; only one problem, his controlling mother has ordered Angus and Dorian to find Henry's mistress...and kill her!
