Xiu gave birth to twins after she disappeared, and had to give them away because she could not raise them. Her parents couldn't forgive her for getting pregnant before marriage, so she died young in depression. Xiu's brother found her letter to her twin father among her sister's belongings. Upon inquiry, she mistakenly thought that the person who was having an affair with her sister was Sun, so she gave the letter to Sun.
Sun and his wife Yang Xilian have been married for 20 years and have no children. This strange letter is like a blockbuster, which makes their delicate relationship worse. Due to mistakes, Yang Xilian abruptly ended her marriage with Sun. With the pain of divorce, Sun embarked on a long journey to the United States to find a son for an old friend. In addition to completing the last wish of the program, Sun also hopes to solve the mystery in his heart, which ungrateful person ruined the life of the program. He definitely didn't expect that person to be his good friend Zhang Danian.
Zhang Danian struggled in the United States for more than 20 years, full of holes and vicissitudes. At present, she is married, beautiful and successful. When he learned that Xiunian gave birth to twins, he clearly knew that he was the biological father of the twins. He can't help but begin to doubt the real purpose of Sun's going to America to find his son. He is worried that Sun's trip will not only ruin his family, but also probably ruin his years of struggle. So on the surface, he helped Sun find his son, but in private, he tried every means to obstruct him, hoping that Sun could give up looking for his son and return to China as soon as possible.
Xiu's two children, Frank and Angela, came to America with their adoptive parents when they were young. Soon after, their adoptive parents died in a car accident, and their brothers and sisters were adopted by different families and lived completely different lives. Angela didn't know that her parents who regarded her as the apple of her eye turned out to be her second adoptive parents. Frank has been wandering around since he was a child, and his experience is very rough. Steven, the second adoptive father, was an alcoholic, which made Frank suffer physical and mental injuries since he was a child. Nevertheless, Frank is grateful to Steven for his meager love, which he cherishes very much. The arrival of Sun undoubtedly hit the hearts of the twins again, and their lives have undergone earth-shaking changes.
Sun never thought of his kindness, but it brought a lot of harm and trouble to the twins. Angela had a nervous breakdown after learning her life story. Frank mistook Sun for his own father and blamed him bitterly. What saddens Sun even more is that Zhang Danian, a former friend, has already drifted away from him under different life circumstances for more than 20 years. Because she had a prenuptial agreement with Susan, a white wife, Zhang Danian was afraid of losing everything she had struggled for many years and dared not admit that the twins were her own flesh and blood. Although Sun hates Danian's cowardice, he still believes with an inclusive attitude that Zhang Danian is still the best of his generation when he can break out of such a world overseas. In order to show off, for the children, for Zhang Danian to continue his career, and for that unforgettable youth, Sun had to assume the responsibility of biological parents on behalf of Zhang Danian to soothe the injured hearts of twins.
Sun's traditional Chinese virtues and selfless noble character not only won the respect of the twins who had nothing to do with him, but also washed away Zhang Danian's once dusty soul and deeply touched his American landlord Meng Xiaoyun. But just as Sun was about to accept Meng Xiaoyun's love, she was surprised to learn that her ex-wife Yang Xilian in China was still infatuated with him and had been waiting for his return. Her divorce from Sun turned out to be another matter. Sun couldn't help falling into a dilemma again. After learning the truth, Meng Xiaoyun supported Sun and Yang Xilian to get back together. Sun returned to the motherland with mixed feelings and the blessings of all relatives in a foreign land, and completed this extraordinary journey of finding children.
As an outstanding representative of Chinese, Sun staged an epic story about finding children in the famous city of angels, which not only touched the Chinese around him, but also won universal praise from the poor to the rich in the United States. Truth, goodness and beauty are like angels with wings, which can transcend blood, race and even national boundaries.
