On the day of their Father’s 70th birthday party, four siblings come to terms with the publication of a novel written by the youngest sibling, that exposes the family’s most intimate secrets.

Pressured by a greedy uncle (Brian Cox) and a pile of debt, lovable loser Steve Barker (Knoxville) resorts to an unthinkable, contemptible, just-crazy-enough-to-work scheme. He pretends to be mentally challenged to rig the upcoming Special Olympics and bring home the gold. But when Steve’s fellow competitors get wise to the con, they inspire him to rise to the greatest challenge of all: becoming a better person.
