Wenjuan (Xu Fan) and Youzhi (Chen Jianbin) have been married for many years. They have raised their lovely daughter Pipi (Chen Yinuo) together, and their lives are calm. However, Youzhi seems to be more and more indifferent at home, so all the burdens and pressures fall on Wenjuan's shoulders. Wenjuan has lived a hard life. In order to prevent her daughter from repeating her mistakes, she decided to send Pipi abroad for further studies. In order to help her daughter learn English, Wenjuan invited Natalie (Gianina Alana Terranova), an au pair from Australia, to provide him with food and accommodation in exchange for her tutoring of Wenwen. A typical Chinese family of three suddenly has a foreign girl. It is conceivable that the days are going by. There are many contradictions and conflicts between the somewhat neurotic Wenjuan and the casual and free-spirited Natalie, which even affect the harmony of the whole family.
