Two guys - a father and a son - are lost when the woman of the house disappears. Why the mother left isn't explained. However, one thing is for sure: these guys need to learn a few things. The husband doesn't even know where is socks are, so how is he or his son going to manage an apartment?
They quickly spring into action, going to a nursing home and looking up a long-lost relative: his mother-in-law. Hey, maybe she'd rather be in our place and can run it, they think.
To their surprise, the mother-in-law is almost "too good to be true." She is a great cook, never complains. Does everything for them. It's unbelievable. Something isn't right and one of the men is puzzled....but why rock the boat?
One day the husband calls his wife to tell her about how good her mother-in-law is acting, and how he's sorry he recommended she go into a nursing home. He winds up getting a big surprise. Another surprise is how he winds up handling the first surprise.
Overall, despite the twist at the end, it's nothing extraordinary, film-wise, to warrant an Academy Award nomination, but these days it doesn't take much.
