Kassie (Jennifer Aniston - Friends, The Break-Up, The Bounty Hunter) is a smart, fun loving, single woman who decides she wants a baby. Despite her neurotic best friend Wally's (Jason Bateman - Arrested Development, Juno, Up In The Air) objections, she chooses to go for this on her own and opts for the services of a charming sperm donor (Patrick Wilson - Watchmen, Hard Candy). Unbeknownst to Kassie, her plans go awry when Wally drunkenly makes a last minute switch that isn't discovered until seven years later when he finally meets her precocious, though slightly neurotic, son. The Switch, the most unexpected comedy ever conceived.
