以漁船作掩飾的英國間諜船—聖喬治號（St.Georges）因為誤撈敵方布下的水雷而令水雷爆炸並令間諜船下沈，而負責控制ATAC通訊器的人員由於船身搖晃，未能及時銷毀ATAC（Automatic Targeting Attack Communicator—自動瞄準攻擊通訊器）通訊器而令發報機連同間諜船下沈。翌日，國防部收到消息，得知間諜船的下沈位置不深，加上ATAC用於導彈發射，使用不當可令英國的中程彈道導彈報銷，最嚴重可令導彈攻擊英國，所以國防部長恐防敵國會搶走發報機。

Alan Turing is the genius British mathematician who was instrumental in breaking the German naval Enigma Code during World War II, arguably saving millions of lives. Turing's achievements went unrecognised during his lifetime. Instead he ended up being treated as a common criminal, for being homosexual at a time when homosexual acts were a crime. In 1952, he was convicted of 'gross indecency' with another man and was forced to undergo so-called 'organo-therapy' - chemical castration. Two years later, he killed himself with cyanide, aged just 41. Alan Turing was driven to a terrible despair and early death by the nation he'd done so much to save.
