Kassie is a smart, fun-loving single woman who, despite her neurotic best friend Wallyβs objections, decides itβs time to have a baby β even if it means doing it herselfβ¦ with a little help from a charming sperm donor. But, unbeknownst to her, Kassieβs plans go awry because of a last-minute switch that isnβt discovered until seven years laterβ¦ when Wally gets acquainted with Kassieβs cute, though slightly neurotic, son.
