Seventy-year-old professor Chen Yuan has been with his wife Li Yuedink for fifty years. He thought he could enjoy his old age in peace, but before his wife died, he discovered that she actually had a complete family - a son, a grandson, and a great-granddaughter. Fifty years of marriage collapsed. What made him even more devastated was that his wife had already made a will, leaving all the property and savings to this "son" Zhang Wei. Overnight, Chen Yuan was kicked out and became a loner. At his most desperate moment, a huge inheritance from his late mother allowed him to stand up again.
