What happens to a rich, neurotic family when one of their own writes a tell-all exposing their dirty secrets? As the Meyerwitz clan prepares for the 70th birthday of family patriarch Henry, Peep World, the expose written by youngest son Nathan has gone red hot. Jack, for instance, the oldest son, is failing in his career and now has to bend over backwards to convince his wife Laura that certain salacious events in Nathan's book weren't really committed by him. Sister Cheri, a drama queen and struggling actress, can see the Peep World movie set from her window, and grows increasingly enraged watching a more successful actress play a horribly unflattering version of her. Over the course of 24 hours, this group of likable and unlikable misfits will summon their courage to come together for the "family dinner" they'll never forget.
