During the Cold War, diplomatic courier Mike Kells must retrieve a dispatch containing top-secret intelligence. But when he arrives at the meeting point, a train station in Salzburg, his contact turns up dead, and the message is nowhere to be found. With no clear suspect in sight, Kells must sort through his uncertain relationships with two women, while sidestepping the pitfalls of subterfuge, sabotage and spies in his search for the documents.
