Each member of a family in Taipei asks hard questions about life's meaning as they live through everyday quandaries. NJ is morose: his brother owes him money, his mother is in a coma, his wife suffers a spiritual crisis when she finds her life a blank, his business partners make bad decisions against his advice, and he reconnects with his first love 30 years after he dumped her. His teenage daughter Ting-Ting watches emotions roil in their neighbors' flat and is experiencing the first stirrings of love. His 8-year-old son Yang-Yang is laconic like his dad and pursues truth with the help of a camera. "Why is the world so different from what we think it is?" asks Ting-Ting. 《一一》道来。年华一帧一帧地逝去。生生死死，春荣秋谢，不过一梦遥——读杨德昌的《一一》。这是你的生活吗?。在隔阂当中充满疲惫，慢慢老去。一一录音简析。人们都太自以为是，其实只是看到一半。【过去未来共斟酌】：《一一》的剧情结构和人生对位。做自己不喜欢的事，怎么会开心。“我这一生没有爱过另外一个人”。 NJ（吴念真）是个很有原则的生意人，同妻子敏敏（金燕玲）、女儿婷婷（李凯莉）、儿子洋洋（张杨洋）以及外婆住在台北某所普通公寓里。小舅子的一场麻烦婚礼过后，因为外婆突然中风昏迷，他迎来更加混乱的日子。 敏敏公司、家里两头跑，时常感觉自己要被耗空；婷婷一直为外婆的中风内疚，恋爱谈到中途发现自己不过是替代品；NJ更是麻烦重重，公司面临破产，他又不愿放下别人眼里一文不值的自尊。一家人里，似乎只有洋洋没有烦恼，他平静地用照相机拍着各种人的背面，帮他们长出另一双眼睛，然而，洋洋简简单单的一句话，道出更深的悲凉。
