In the old alleys deep in the city, the lives of three generations of the Lin family are like tangled vines, full of constant emotional entanglements. Retired teacher Lin Zhengde suddenly suffered a stroke. This accident, like a stone thrown into a calm lake, aroused the long-hidden conflicts in the family. The eldest son Lin Jianjun has a successful career, but he has a grudge against his father due to an old misunderstanding; the younger daughter Lin Xiaomei has a marital rift, but she forces a smile in front of her family.
When the burden of life is suddenly pressed down, past grievances, secret thoughts and real dilemmas are intertwined. Mother Zhao Xiulan maintains the balance of the family in trivial matters, Lin Jianjun struggles between responsibilities and emotional ties, and Lin Xiaomei re-examines herself in marriage and family relationships. Through repeated collisions and understandings, they gradually understood that the bond between family members may be full of obstacles, but they are always the warmest support for each other. The story under the roof contains tears, disputes, and hope and love rising in difficult situations.
