Officer Karl Torok's best friend, Count Alvinczy, is elected president of the Hungarian cabinet. Meanwhile, Alvinczy's wife, Madalaine, receives a message from a blackmailer, threatening her husband. When the blackmailer winds up dead, Madalaine appears to be the most likely suspect. Torok, however, knows the case is more complicated than it seems and dedicates himself to revealing the truth behind the mystery.
