Jack Sadelstein is a successful advertising executive in Los Angeles with a beautiful wife and kids, who dreads one event each year: the Thanksgiving visit of his identical twin sister Jill. Jill's neediness and passive-aggressiveness is maddening to Jack, turning his normally tranquil life upside down.
Rated PG by the Motion Picture Association of America for crude material including suggestive references, language, comic violence and brief smoking.
