In 1940s Shanghai, beautiful young Jiazhi spends her days playing mahjong and drinking tea with high society ladies. But China is occupied by invading Japanese forces and things are not always what they seem in wartime. Jiazhi's life is a front. A patriotic student radical, her mission is to seduce a powerful employee of the occupying government and lead him to the assassin's bullet. Yet as she waits for him to arrive at their liaison, Jiazhi begins to wonder if she is cut out to be a femme fatale and coldly take Mr. Yi to his death. Or is she beginning to fall in love with him? A passionate tale of espionage, deception and love, "Lust, Caution" is accompanied here by four further dazzling short stories by Eileen Chang.

Lust, Caution captured the Golden Lion from the 2007 Biennale Venice Film Festival, making Lee the winner of the highest prize for the second time in three years. When Lust, Caution was played in Lee's native Taiwan in its original full-length edition, it was very well received. Staying in Taiwan to promote the film and to participate in a traditional Chinese holiday, Lee got emotional when he found that his work was widely applauded by fellow Taiwanese. Lee admitted that he had low expectations for this film from the U.S. audience since "its pace, its film language – it's all very Chinese."Lee was chosen as president of the jury for the 2009 edition of the Venice Film Festival that took place from September 2 to 12, 2009.
