The Focker family is about to grow: Son Henry announces that he wants to marry his girlfriend Olivia (Ariana Grande). This puts his father Greg (Ben Stiller) in a dilemma, because he views the relationship with great suspicion. In his opinion, he’s right to be, since Olivia is an FBI negotiation expert who knows how to manipulate people. So he takes a closer look at his future daughter-in-law, using questionable methods reminiscent of those of his own father-in-law, Jack (Robert De Niro).
