Tian Wenjun (Huang Bo) and Lu Xiaojuan (Hao Lei) were once a loving couple, but the relationship between them was exhausted by time and quarrels, and finally they chose to divorce. Now, the only hub connecting the two is their lovely son Tian Peng. However, one day, this only bond was broken. Tian Peng disappeared for no reason when he went out to play. In despair and collapse, Tian Wenjun and Lu Xiaojuan embarked on a long journey to find their son, and met many fathers and mothers who were as helpless as them on the way. Time passed quickly, and a clue about Tian Peng surfaced, prompting Tian Wenjun and his wife to come to a remote village, where they saw a boy who looked like Tian Peng. However, the "mother" in the boy's mouth was not Lu Xiaojuan, but a village woman named Li Hongqin (Zhao Wei). What is going on with all this dislocation?
