Mother-in-law shows up and moves in with a married couple. She likes her son-in-law to call her "mommy"...and under pressure of his wife, he agrees not to say no to her. But as they get closer, he gets oddly comfortable with the situation...until his wife has to go off for a business trip while he's down with a bad cold, and "Mommy" takes care of all of his needs...and he can't say no, even if he wants to.
