Margaret Tate (Sandra Bullock) terrorizes her publishing house co-workers with her abrasive, take-no-prisoners management style, especially her overworked assistant Andrew Paxton (Ryan Reynolds). But when Margaret is threatened with deportation to her native Canada because of an immigration technicality, the quick-thinking exec announces that she and Andrew are engaged to be married. Ambitious Andrew agrees to go along with her scheme—if there’s a long-awaited promotion in it for him. Everything is going according to Margaret’s plan, until an overzealous immigration official makes it his business to prove that the couple’s engagement is bogus. To demonstrate her commitment to her new fiancé, Margaret agrees to celebrate the 90th birthday of his colorful grandmother (Betty White) — in Alaska. The editrix’s type-A ways put her at odds with her eccentric future in-laws with hilarious consequences, until the Paxtons teach Margaret a thing or two about family.
