You can live with someone without knowing them, but in most cases at least the co-habitants have been properly introduced. Not so in writer/director Leight's first film. When stockbroker Brian (Anderson) moves in with his fiancée, he assures his drinking buddies he'll keep his Greenwich Village bachelor pad for a couple of nights a week. He instructs his secretary to sublet it on the free days. That suits Sam (Broderick) just fine. He can't afford a place of his own, but craves escape from his crowded flat-share, even if only at weekends. Then there's Ellen (Sciorra), a frustrated housewife looking for a pied-à-terre in the city. She gets Mondays and Fridays. Brian and Sam swap nights, unbeknown to Ellen, who assumes that the former is the sensitive, tasteful gourmet who leaves her presents, and that Sam is the slob who treats the flat like a tip. When she decides to have an affair, she chooses the wrong man. The film has three amiable leads and doesn't overstay its welcome.
