The bickering Hubbards and Buells are stunned when their kids return from a night out announcing they’re engaged. After arguments about the wedding plans are finally settled (amid the kids’ breaking up over a fight about whose mother is right), the kids wind up eloping with another couple, while their parents are trying to rescue Kaye’s beloved grand piano, set up in the Hubbards’ back yard for the next morning’s nuptials, from a midnight...

The Hubbards sell their old refrigerator to the Buells. When it breaks down, the Buells retaliate by launching a raid to steal the Hubbards’ new one.

A heated argument leads to Roger challenging Herb to a duel at dawn. While they practice with fencing foils, their wives conspire to stop the showdown.

Going to a store to return a duplicate wedding gift for the kids, the mothers, who have been banned from their own phones for continually calling the honeymooning couple, spend $15.70 talking to them on a payphone, unknowingly getting locked in the store when it closes. With only one dime left, they accidentally reach a sleeping bullfighter in Barcelona, whom they beg to relay their SOS to their husbands. Madness ensues when a security guards finds...

A fugitive bank robber holds everyone at gunpoint at the Hubbards’ home, whiling away the time reciting poetry and playing gin rummy, and everyone hopes that Kaye’s newly acquired karate skills will help them escape.

Checking out the place that the kids have rented, the mothers return their deposit and fix up the Hubbards’ garage apartment for them. After their snooping gets them caught hiding in the kids’ shower, they promise not to interfere, but their curiosity gets to them when they see friends arriving for a dinner party. Peeking in the electric garage door windows, they wind up spending the evening lying atop the horizontal door after Jerry opens it...

Jerry decides to major in dramatic arts, giving everyone the showbiz bug. Suzie and all four parents tune up to help him audition for the school musical.

The Hubbards and the Buells show up at the same resort, and when their honeymooning kids unexpectedly arrive, having been rained out at their original destination, the in-laws spend a sleepless night together in a cramped room, giving the only other available room to the kids. Desi Arnaz, Jr. can be seen in a golf cart in the opening scene.

Kaye borrows a blonde wig from Eve, and Roger’s romantic reaction succeeds only in depressing Kaye, who’s convinced that he now prefers blondes.

The Hubbards and Buells work up acts to go to Mexico to be on a variety show hosted by their matador friend. Desi sings “The Straw Hat Song” with Desi, Jr. on drums; Eve and Kaye sing “Turn Around.”
