Tom (Steve Martin) and Kate Baker (Bonnie Hunt) continue to juggle the demands of an extra-large brood in this sequel that has the family meeting its nemesis in the form of the equally gigantic Murtaugh clan. Led by an overly competitive patriarch (Eugene Levy) and his sexy new wife (Carmen Electra), the Murtaughs are hell-bent on wrecking the Bakers' idyllic lake vacation in this supersized comedy co-starring Hillary Duff and Piper Perabo.
