影片改编自美籍俄裔作家弗拉基米尔·纳博科夫1964年的小说《卢金的防守》,讲述了一个因为从小受到老师的虐待而变得孤僻的国际象棋冠军亚历山大·卢金和一个意志坚强的上流社会女性娜塔莉亚之间的爱情故事。Set in the late 1920s, The Luzhin Defence tells the story of a shambling, unworldly chess Grand Master who arrives in the Italian Lakes to play the match of his life and unexpectedly finds the love of his life. Discovering his prodigious talent in boyhood overshadowed by his parents' failing marriage, Luzhin's lyrical passion for chess has become his refuge and rendered the real world a phantom. Already matched up by her family to the very suitable Comte de Stassard, when Natalia meets Luzhin, she is drawn to the erratic genius and offers him a glimpse outside of his chess obsession. But it is a world he is not equipped to deal with and his two worlds collide to tragic effect.
