Lust, Caution

During the Second Sino-Japanese War, a shy, inexperienced university student, Wong Chia Chi, travels from Shanghai to Hong Kong and attends her first year at Lingnan University. A male student, Kuang Yu Min, invites her to join his patriotic drama club, and soon she becomes a lead actress, inspiring both her audience and her colleagues. Inspired by the troupe's patriotic plays, Kuang persuades the group to make a more concrete contribution to the war against Japan. He devises a plan to assassinate Mr. Yee, a special agent and recruiter of the puppet government of Wang Jingwei set up by the Japanese occupation in China. The beautiful Chia Chi is chosen to take on the undercover role of "Mrs. Mai", the elegant wife of a trading company owner. She manages to insert herself into the social circle of Mrs. Yee.
