A cute, drunk realtor (Shu Qi), dating her married boss, pukes on a single, sober cop at a Beijing hotel after partying. They keep bumping into each other after that.

A beautiful real-estate agent (Peiru) gets drunk at a karaoke bar and throws up on a principled, lonely cop (Zhendong). Zhendong quickly falls for the flirtatious Peiru despite the fact that she's having a tortuous affair with a married man. As Peiru gradually abandons her materialistic values and falls in love with the good hearted Zhendong, it becomes apparent that he is suffering from a disease that is robbing him of his mental faculties.—Anonymous
