Shanghai, 1942: The World War II Japanese occupation of this Chinese city continues in force. Mrs. Mak, a woman of sophistication and means, walks into a café, places a call, and then sits and waits. She remembers how her story began several years earlier, in 1938 China. She is not in fact Mrs. Mak, but shy Wong Chia Chi (Tang Wei). With WW II underway, Wong has been left behind by her father, who has escaped to England. As a freshman at university, she meets fellow student Kuang Yu Min (Wang Leehom) Kuang has started a drama society to shore up patriotism. As the theater troupes new leading lady, Wong realizes that she has found her calling, able to move and inspire audiences and Kuang.

He convenes a core group of students to carry out a radical and ambitious plan to assassinate a top Japanese collaborator, Mr. Yee (Tony Leung). Each student has a part to play; Wong will be Mrs. Mak, who will gain Yees trust by befriending his wife (Joan Chen) and then draw the man into an affair. Wong transforms herself utterly inside and out, and the scenario proceeds as scripted until an unexpectedly fatal twist spurs her to flee.

Shanghai, 1941: With no end in sight for the occupation, Wong--having emigrated from Hong Kong--goes through the motions of her existence. Much to her surprise, Kuang re-enters her life.

As Wong reprises her earlier role, and is drawn ever closer to her dangerous prey, she finds her very identity being pushed to the limit...
