Jennifer Aniston stars alongside Jason Bateman in this offbeat comedy as Kassie, a smart, fun-loving single woman who, despite her neurotic best friend Wally's (Bateman) objections, decides it's time to have a baby - even if it means doing it herself...with a little help from a charming sperm donor (Patrick Wilson). But, unbeknownst to her, Kassie's plans go awry because of a last-minute switch that isn't discovered until seven years later...when Wally gets acquainted with Kassie's cute - though slightly neurotic - son. From the people behind Little Miss Sunshine and Juno comes The Switch.
