After four decades in show business, the husband and wife comedy team of Jerry Stiller and Anne Meara finally make their big-screen debut together in this story about a marriage on its last legs. Sam (Stiller) and Molly (Meara) have been married for over 40 years. Their children are grown and living on their own, and the romance has drifted out of their relationship; arguing has become their favored method of communication. But the bickering goes too far when Molly asks Sam to get rid of the carp he's keeping in the tub in their guest bathroom. Sam informs Molly that if she doesn't like the fish, she can leave -- and Molly takes him up on the offer, moving in with their son Joel (Mark Ruffalo). This is hardly good news for Joel, who is having problems with his wife and feeling tempted to stray by an attractive blonde at work. Meanwhile, Sam and Molly's daughter Ruth (Jane Adams) tries to convince her father to win back her mother, but Sam receives some surprising competition when Molly starts dating an old friend named Lou (Bob Dishy).~ Mark Deming, All Movie Guide
