A Hong Kong father and Chinese daughter live in different regions and speak different languages. With their identity and lifestyle antithetical to each other, family members who are supposed to be the closest are actually the most unfamiliar. CHAN Wing-keung, an elderly man who lives alone, is a security guard at a Kwun Tong park. One day, he accompanies his daughter Tsz-shan, who comes from Chinese Mainland, to renew her ID card and open a bank account in Hong Kong. They return home and go for a walk at the park where Wing-keung works. Faced with the gap between them, they are hesitant to speak and can only beat around the bush without making a move. The film gazes at the Hong Kong’s cityscape while ruminating sea changes between father and daughter with its shifting aspect ratio. Once again, Hong Kong Film Award-winning actor Tai Bo acts out the loneliness of elderly in a surehanded performance.
