In 1954, six strangers arrive by ominous invitation at a secluded New England mansion, despite most of the guests being from the Washington, D.C., metropolitan area. Greeted by Wadsworth the butler, each guest receives a pseudonym. Wadsworth explains to them that their "host", Mr. Boddy, is the one who has been blackmailing them for years. He is then killed and all are suspects in the murder. Before the police arrive, they will try to find out who did this, but other people are found dead, which makes things worse.
