The Misidentified Kin

When her husband's assistant locks an elderly woman in a restaurant storage room, everyone assumes it's the wife's mother—including the husband, who defends his assistant and calls the victim a freeloader. But at his mother's fiftieth birthday gala, the wife reveals the dead woman was his own mother, whom she had cared for alone through years of dementia. As the truth collapses around him, the husband destroys everything he claimed to love, and the wife walks away free.
