The Hoover family -- a man (Greg Kinnear), his wife (Toni Collette), an uncle (Steve Carell), a brother (Paul Dano) and a grandfather (Alan Arkin) -- puts the fun back in dysfunctional by piling into a VW bus and heading to California to support a daughter (Abigail Breslin) in her bid to win the Little Miss Sunshine Contest. The sanity of everyone involved is stretched to the limit as the group's quirks cause epic problems as they travel along their interstate route.
