<p>　　故事发生在二战期间的英国。汤姆·杰里科是一名出色的密码破译专家，他在布兰彻利公园密码破译中心工作，帮助盟军破解代号为“谜”的密码。在这里，他与一位女雇员，克莱尔·罗米利发生了一段短暂而炽烈的感情。克莱尔美丽动人，但却是个谜样的神秘女子，在她身上似乎隐藏着不少秘密。尽管如此，在破译中心她还是吸引了大批的追逐者，汤姆仅仅是其中的一个罢了。 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　而对汤姆来说，自从5年前战争爆发他开始这份辛苦的工作以来，他就没有再享受过生活的乐趣和爱情的甜蜜，因而他很快就陷入了对克莱尔深深的迷恋中。不过，显然克莱尔并不投入，她不久就厌烦了，并提出分手另结新欢。汤姆顿时一蹶不振，工作时也心不在焉。这种沮丧和痛苦终于被傲慢的上司激发出来，他冲动地对上司大打出手。这一举动使他被调职，但不料一个月后，他竟然又被调回了中心。 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;　　此时的布兰彻利公园正处于一片混乱中，面临着一场灾难...</p>
