Eighty-year-old Jin Mao lives alone in a townhouse in Pingxi. His wife has passed away, and his children have settled down in Taipei. Although his health is declining, Taipei is still a place that Jin Mao will never get close to. The hospital is almost his only impression of this city. One day, Jin Mao was hospitalized again due to stomach pain. In the ward, his children, who have entered their prime, quarreled again about his care. However, an accident made Jin Mao live in a nursing home. Even when his grandson Kaikai brought the good news of his marriage, Jin Mao's low mood was not eliminated at all. On this day, his daughter pushed Jin Mao on a wheelchair and took him to the street to order a new suit for her grandson's wedding. Little did he know that for Jin Mao, suits already had a completely different meaning.
