A routine wartime tale of double-crossing spies and Nazi evils, The Enemy General is about the stereotypical, not exceedingly brilliant, and crass fascist Gen. Bruger (John Van Dreelen) who is one of the targets of the French Resistance movement. When Lemaire (Van Johnson) gets the unwanted assignment of safely escorting the evil general to England, he is especially torn up about the job. Gen. Bruger was responsible for killing a dozen hostages, among them Lemaire's fiancée. As he sets off with the general, Lemaire has been told that the man has valuable information to give to the British, and that is why he needs to get him safely to England. On the other hand, Lemaire begins to piece things together and eventually realizes that the general is as Nazi as ever and has every intention of betraying British secrets to the German high command.
