He receives the identity of Richard Ashenden and is introduced to the womanizer killer The General that will meet him in the Hotel Excelsior in Switzerland to assassin a German spy. On arrival, Ashenden is surprised to know that his wife, arranged by his superior, is waiting for him in his room. When he enters the room, the hotel guest Robert Marvin is flirting with his beautiful wife, Mrs. Elsa Ashenden. When Marvin leaves the room, he learns that Elsa accepted the job because of the money. Ashenden goes with the General to a church to meet the organist, who is their contact, to learn who the German agent is, but they find him dead with a button in his hand. They head to the casino to meet Elsa and accidentally they find that the button belongs to a man named Caypor. They start a conversation with him and convince Caypor to climb a mountain with them. They leave Elsa with his wife, Mrs. Caypor, and while on the top of the mountain, the General pushes off a cliff and kills Caypor. But on the next morning, they receive a telegram informing that Caypor was not the agent. Now they have to find the agent while Elsa decides to quit her job. They go to a chocolate factory and discover the identity of the German spy, but he is on the run.
