Five years later, her third son Michael begged her to attend his wedding. She decided to return to the estate. Unexpectedly, she met her three daughters-in-law who had never seen her before. Those three women cursed and insulted her, completely unaware the haggard rural woman was their mother-in-law. Finally, the truth was revealed, and the three daughters-in-law regretted what they had done deeply.
