冷戰時，全球兩大特工組織——俄羅斯“中心”與英國“圓場”明爭暗斗。特工遇害，高層震怒，責成“圓場”挖出“地鼠”。懷疑對象共有5人，即圓場上任“老總”命名的鍋匠，裁縫，士兵，窮人，乞丐。其中，金盆洗手的“乞丐”喬治·史邁利(加里·奧德曼 Gary Oldman 飾)本來有重大嫌疑。某日，行動組-剝頭皮組頭目的彼得·吉勒姆(本尼迪克特·康伯巴奇 Benedict Cumberbatch 飾)與英國內閣辦公室諜報總監拉康排除了史邁利的嫌疑，令其重新出山，負責挖出“地鼠”。于是，史邁利開始分別走訪故人，調查“圓場”老大阿勒萊恩，裁縫-比爾·海頓(科林·費斯 Colin Firth 飾)，士兵-掌管東歐事務的資深間諜羅埃·布蘭德，窮人-后勤部門點路燈組組長托比·伊斯特哈斯。一時間，圓場疑云密布，人人自危，究竟誰才是“地鼠”……　　本片本片根據約翰·勒卡雷的同名小說改編。片名來自英國民間的“鵝媽媽童謠集”。

 少女梅寶（佩珀·柯達 Piper Curda 配音）偶然借助突破性技術，讓自身意識“跳脫”身體，進入機械動物體內，“變身”為一只活潑靈動的河貍，從而得以潛入動物社群內部，更以“人類思維闖入動物本能”的獨特視角，揭開一場充滿意外與溫情的野外探險。

　　World War II is around the corner, but the only thing Sally Bauer can think of is the ocean. Her dream is to swim across the English Channel. Her father has tried to exorcise her obsession with swimming since she was a toddler, without success. An unwanted pregnancy forces her to abandon her dream – and herself. The child’s father does not want to be involved, so as a woman in the ‘30s in Sweden, Sally has no choice but to do what is expected of her: to be a mother. There is no place left for her dreams and Sally is pulled into bottomless darkness, until her sister Carla saves her. With renewed purpose, together the sisters begin to dismantle the conventions they are constantly facing. In late August 1939, Sally stands on the shore at Dover and takes her first step into the English Channel. She swims across the open and icy sea for 15 hours, waving to the Navy who are readying for war. A couple of days after Sally swims ashore at Calais, Poland is invaded.
