Jennifer Aniston stars in this romantic comedy based on a short story by Jeffrey Eugenides. Desperate to have a baby before it is too late, 40-year-old singleton Kassie (Aniston) chooses the artificial insemination route and employs the services of suave sperm donor Roland (Patrick Wilson) despite the protestations of her best friend Wally (Jason Bateman). Wally, who has long been secretly in love with Kassie, gets drunk at Kassie's 'insemination party' and ends up accidentally spilling Roland's sample. In a panic, he replaces it with his own. Seven years later, when Kassie returns to New York with her son Sebastian (Thomas Robinson), Wally must finally face up to the consequences of his actions.
