U-Boat Wargamers
二战期间，纳粹德国的U型潜艇频繁在大西洋上伏击英国商船。由于无法知晓U型潜艇的战术，英国皇家海军苦于无法找到并击退它们。机缘巧合，他们转向一支年轻女性团队，即英国皇家海军女子服务队（WRENS）。通过在巨大的棋盘上模拟大西洋海战的战况，她们最终解读出了U型潜艇的战术，找到反潜的方法，并设计出众多绝妙的海战战术。英国皇家海军女子服务队最终成为了二战期间最杰出的智囊团之一，但她们的故事一直被忽视。现在，这些被遗忘的故事得以讲述。 节目结合情景再现、CGI技术、彩色档案影像和幸存的英国皇家海军女子服务队成员的证词以及历史学家的精彩讲述，生动呈现了这一史诗般时期的奋斗、生存和胜利的故事。
