Zhao Kai runs a restaurant called Filial Family Banquet. In front of the cameras, he always puts on a show of being a devoted son, but in private, he considers his rural parents an embarrassment. He even passes off the ancestral sauce his father brings him as a 'secret recipe from overseas.' After the relocation and redevelopment, his parents receive a row of commercial properties, and only then does Zhao Kai discover that his restaurant is actually rented from his own father. What his father takes back is not his son's livelihood, but the name and dignity that were stolen from him. His daughter, Zhao He, stands by her parents and upholds the rules when times are hardest. Now that his fake filial piety has lost its signboard, can the son finally learn to come home through the front door?
