Childhood friends Tommy and Tuppence meet in London after having served in World War I. Recently "demobed", short of money, and with no job prospects, they decide to become adventurers for hire. Soon, they are employed by the British Government to locate a secret treaty signed before the war.
影片拍摄于1967年,是至今为止关于伟大的音乐家巴赫最优秀的影片,片名来源于英国作家同名小说,片中引用的对话、信件都取自巴赫生前的真实文件档案。影片几乎汇集了当时音乐演奏界的精英,如哈侬考特、奥古斯特·温钦格等,具有非常高的史料价值。与我们平日看到肖像画上胖而结实的巴赫完全不同,由著名钢琴演奏家和指挥家古斯塔夫·莱昂哈扮演的巴赫显得瘦小文弱。影片问世后得到了当时影评界的激赏。
