Meet the Fockers (2004)

Having managed to enter the longed-for "circle of trust" after the events in Meet the Parents (2000), Greg Focker invites the straight-laced Byrnes family to meet mum and dad, the eccentric Fockers. However, as conservative Jack and Dina finally get to meet the uninhibited, cool parents Bernie and Roz, rivalries and secrets emerge, and someone learns a new word. But there's still something fishy about Greg. Will Jack resort to using his infallible contraptions to get to the bottom of Greg's suspicious behaviour?
