Chen Yuan and his wife Li Yue have been together for fifty years and have always lived the DINK life they agreed on. He broke with his family for this reason and regarded his wife as his only sustenance in life. However, when Li Yue was dying, he saw his middle-aged son, grandchildren and even great-granddaughter kneeling on the floor in the ward. The oath he had kept for half his life turned out to be a complete lie. After Li Yue died of illness, his son Zhang Wei took his mother's will and kicked out the 75-year-old Chen Yuan on the grounds that the property was in Li Yue's name. Chen Yuan, who was in a desperate situation, was unexpectedly informed by a lawyer that his mother, who had passed away many years ago, had left him a trust fund worth 80 million.
