Hard-to-crack ex-CIA man Jack Byrnes and his wife Dina head for the warmer climes of Florida to meet the parents of their son-in-law-to-be, Greg Focker. Unlike their happily matched offspring, the future in-laws find themselves in a situation of opposites that definitely do not attract.

Greg Focker is ready to marry his girlfriend, Pam, but before he pops the question, he must win over her formidable father, humorless former CIA agent Jack Byrnes, at the wedding of Pam's sister. As Greg bends over backward to make a good impression, his visit to the Byrnes home turns into a hilarious series of disasters, and everything that can go wrong does, all under Jack's critical, hawklike gaze.
