Carl Hamilton is in one sense a peculiar sort of secret agent in that he has a license to kill but applies his conscience to that license far more often than is comfortable for him. In another sense, since he is Swedish, it makes sense that this would be so. In this story, one of a series of successful films based on this character from the novels of Jan Guillou, he has been given the task of infiltrating a group of terrorists operating out of Hamburg, who reportedly intend to attack the U.S. Embassy in Stockholm. After falling in love with one beautiful terrorist, he attempts to get her to change her ways by the force of moral persuasion rather than arms.
