David Remon loves barmaid Dulcie, not by choice but by force of circumstances, and attempts to persuade her to marry him rather than submit to a life of drudgery. But Dulcie is thoroughly independent and prefers to earn her own living.

The Mummy and the Humming-Bird recounts the tragedy of a neglected wife who seeks amusement in the company of an unscrupulous Italian novelist whose only object in making love to her is the hope of eventually accomplishing her downfall. The reawakening of the unsuspecting husband, the revenge of which a former victim of the wily schemer wreaks, and the saving of the innocent woman are fraught with thrills and dramatic suspense in abundance. It is the sort of production which can not but impress those who view it. This film is lost.
