Archie Rice, an old-time British vaudeville performer sinking into final defeat, schemes to stay in show business.

After he is orphaned by an air raid on Port Said during the Suez Crisis, a young boy attempts to go by himself from the Suez Canal to Durban in South Africa where his nearest relative, Aunt Jane, lives. On the way he meets a variety of different people who help or hinder his journey - including an ageing diamond smuggler.
