As described in a film magazine, Jasmine Grenfel (Heming) forsakes her suitor Ian Stafford (Tearle) and marries Rudyard Byng (Lucas), who has worked his way up to the top rungs of success in the African diamond mines of the
Transvaal. Stafford, saddened, goes to Africa. During the three years that follow Byng becomes dissipated. Adrian Fellowes (Doucet), his secretary, has intrigues with several women including the dancer Al'Mah (Deshon). He has also paid some attention to Jasmine, which has aroused the dancer's jealousy. Fellowes is found murdered and the husband and wife both suspect each other of the crime. At the outbreak of the
Boer War Byng joins the army and Jasmine and Al'Mah join the
Red Cross. The battles that ensue bring out the manhood of Byng. Al'Mah is struck by a fragment of a shell and in a dying confession admits the murder of Fellow. Jasmine and Byng are later happily reunited. == Cast ==
