Cleaner Zhou Dayou locked his autistic daughter Ayue at home while attending a banquet. Frightened, the girl climbed the balcony to look for him and fell, hanging dangerously on the 15th-floor air conditioner shelf. Old Lin, who was once framed by Zhou, set aside his grievance and risked his life to save her. Overwhelmed with guilt, Zhou reformed completely: he quit drinking, worked diligently, sold his belongings to pay for his daughter’s rehabilitation, and publicly cleared Old Lin’s name. In the end, the two partnered to start a housekeeping company. Zhou’s family regained happiness, and Old Lin became their dearest family.
