Spring Fever is a 2009 Chinese film directed by Lou Ye. The production of the film is in defiance of a five-year ban on filmmaking imposed by China's State Administration of Radio, Film, and Television (SARFT) for his previous film, Summer Palace. Filmed in Nanjing, the film was described to be about a young threesome overcome with erotic longings.
By the time of the film's premiere at the Cannes Festival on 13 May 2009, it was known that Lou had circumvented the five-year ban imposed upon him after Summer Palace by having Spring Fever registered as a Hong Kong/French co-production.
The story begins in Nanjing. Suspecting that her husband Wang Ping is cheating on her, Lin Xue hires an unemployed photographer named Luo Haitao to follow him. Indeed, Wang is having a steamy affair with Jiang Cheng, a gay man. Lin confronts Wang and storms into Jiang's office to make a scene. Jiang cuts off all contact with Wang. He becomes depressed and hooks up and has sex with Luo. Luo actually has a girlfriend Li Jing who loves him.
Wang becomes desperate and commits suicide. Meanwhile, Li's factory is shut down by the police. As her boss has been good to her, Li helps to secure his release from detention, but comes to the realization he just wants to get into her pants.
Jiang is devastated after hearing Wang's suicide. He quits his job and plans to go to Suqian with Luo for some materials. However, Li tags along and discovers their relationship. She is very upset but as she really loves Luo, decides to "share" him with Jiang.
On their way back to Nanjing, it becomes clear the dysfunctional love triangle cannot be sustained. Li leaves first, and Luo and Jiang also break up with some tears shed. Jiang is ambushed by a vengeful Lin and almost killed. He recovers and begins a relationship with another gay man.
