At a dinner celebrating the 70th birthday of their father Henry Meyerwitz (Ron Rifkin), tensions among the four Meyerwitz siblings explode thanks to the success of the youngest son, Nathan (Ben Schwartz), whose new novel ''Peep World'' is a thinly veiled portrait of the family. The best-selling expose reveals the oldest, "responsible" son, Jack (Michael C. Hall), as a porn addict, the daughter, Cheri (Sarah Silverman), as a catty wiktionary:drama queen, and the third son, Joel (Rainn Wilson), as a living disaster with a loony plan to change his life.
