Expanded from a two-character play by Murray Schisgal, this comedy stars Eli Wallach as Ben Harris, a disgruntled New York City mail carrier. Harris is fed up with being cheated by his landlords, the Kellys (Roland Wood and Ruth White), so he terrorizes them and the city's housing authority until they agree to give him a new apartment. Not satisfied, Harris "goes postal" by kidnapping a bored suburban housewife, Gloria Fiske (Anne Jackson) and taking her back to his apartment. To his surprise, he finds that Gloria also hates the world, and they become fast friends. He eventually lets her go but follows her home. When he tries to climb into her window, her husband Jerry (Bob Dishe) chases him away. Harris returns to his apartment building, where the Kellys invite him in to watch TV, and somehow this soothes his wrath. Dustin Hoffman has a small role as a hippie named Hap.
