Eight strangers are invited to spend the weekend at an Austrian castle in the Alps. At the chateau, accessible only by cable car, they are received by the Grohmanns, a servant couple who have never seen their employer. As the holiday commences the guests assemble to hear the host's recorded welcome. Among them are singer Mike Raven, Judge Cannon, private investigator William Blore, actress Ilona Bergen, alcoholic Dr. Armstrong, retired General Mandrake, secretary Ann Clyde, and the American Hugh Lombard. In his message their host discloses that each is a murderer and will be executed over the weekend. Guests and servants are slain in rapid succession, until only Ann and Lombard remain. Although they have fallen in love, the secretary shoots the American. Returning to the castle, she finds the presumably slain jurist awaiting her. Certain of Lombard's death, Cannon proclaims himself the host. Reminding Ann that she will undoubtedly be convicted of the murders, the magistrate reveals that he has poisoned himself and will be dead upon arrival of the authorities. As the judge speaks, the American enters the room. While awaiting the police, the lovers describe their mutual defense pact and verify their common innocence.
