Seventy-year-old Qin Shoucheng breaks his leg and urgently needs surgery, but his three sons, who hold four relocation apartments, pass the buck to one another and no one is willing to pay. His daughter Qin Lan takes out her daughter's tuition money to treat her father. Qin Shoucheng digs out the maintenance agreement signed when the houses were divided back then, and resolves to take back the real estate. Faced with his sons' sophistry, instigation, and pressure, he breaks through the shackles of family affection, clarifies the boundaries between family affection and real estate, and ultimately guards his own retirement foundation while re-evaluating family and affection.
