郑晋康，83岁，未婚无子女。影片用摄像机记录了他对前半生跌宕起伏的口述和如今安老院孤独生活的状态。 出生百万富豪家族，当年上海滩上的小K，从小出入跑马厅、舞厅等上流社会场所，人生前20年生活在纨绔子弟的富足之中；1950年开始人生命运急转直下，接连的政治运动和莫须有的罪名，把他打成了反革命并两次入狱几十年；晚年的他偏安小镇双林，独居安老院，因脾气乖戾不愿与他人同住，执意独居太平间。安老院孤独生活的间隙，老人坐在床头滔滔讲述故去的声色犬马和落难后的牢狱之艰。 片尾，面对镜头，老人慷慨地讲出他已将自己的后事托付给上海的老朋友。 他高唱着《满江红》，脑海中依旧萦绕着那句让他悔恨终身的诗句：“莫等闲，白了少年头，空悲切”。 Zheng Jingkang is 83 years old and single with no child. This film has two parts, one that records the narration of his first half life full of quirky twists and the other that describes his lonely life in QingEn residential care home. Zheng Jingkang was born in a millionaire family and often patronized the horse gambling racing and dancing clubs. So he lived a comfortable life when he was young. But since 1950s, successive political movements and unwarranted charge turned him into a counter-revolutionist and he was put into the prison twice for several decades. In his old age, he lived in a residential care home in Shuangling Town. Being bad-tempered, he insists on living alone in the reposing room. He tells of his past entertainments and prison life at leisure while sitting on the bed. At the ending，he tells us that he has asked one friend of his to take care of his funeral affairs. He sings The Rive All Red loudly, with the haunting line that gives him a lifelong regret, Do not let it slip away; When a young man’s head turns grey, Regret will be too late.
