Zhu Xiaobei (played by Zhou Yun) and her husband Chen Yan (played by Sun Honglei) have been married for three years. She has less and less enthusiasm for each other. Photographer Guo Qing (played by Ding Zhicheng) was divorced by his wife and ended up running away from home. After the divorce, he walked in the desert with his camera on his back. In loneliness, he seemed to understand something, and secretly vowed not to believe in the so-called love. After returning to Beijing, he met Zhu Xiaobei who was looking for passion. Both men and women seem to have touched the most sensitive point, causing both parties to fall into pain and entanglement. Xiaobei cares about her husband's love for her, while Guo Qing blames her inner promise. When Chen Yan discovered that her wife was different, Wang Liqin (Yan Xiaopin), an unfortunate female colleague in the work unit, began to look at him with her eyes. At first, Chen Yan pretended to be a fool with a responsible attitude to her family, but things quickly went off track.
