Kassie, a smart, fun-loving single woman who, despite her neurotic best friend Wally’s 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. 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.
