Mrs Hook made her exit from a troubled world when her husband was about thirty years of age. As some compensation for her early departure she bequeathed him a legacy in the shape of a daughter, Sally, who, in addition to a pretty face and an excellent voice, possessed a remarkable aptitude for business. By force of her character and her shrewdness, plus her invention of a wonderful liqueur, Mr Hook eventually finds himself at the head of a thriving establishment and with a considerable fortune in the bank.
One day he happens to drop from his pocket the recipe of the precious liqueur. It is picked up by a loafer who, for a consideration, passes it on to Captain Adrian Paap, a dashing officer in love with Sally, and who thinks the possession of the little bit of paper will considerably help his cause with the distiller's daughter. But the young lady has given her heart, and she intend to follow up with her hand, to a handsome bandmaster. Being a lady of some character she carries her point and brings the piece to a satisfactory conclusion.
