Richard Hannay’s ordinary life is shattered when he receives a frantic visitor, Scudder, who tells Hannay of a sinister plot by anarchists to assassinate the Greek Premier. Hannay allows the man to stay in his flat to hide out. Scudder writes down the whole plot in a black note book. One day Hannay arrives to the flat to find it ransacked and Scudder dead with a knife in the back. Thinking the police would not believe he was innocent, Hannay becomes a man on the run, pursued under false pretenses by the police and evil anarchists.
