Isaac Abrahams and his daughter, Helen, who are in fairly good circumstances, are seen taking care of their jewelry shop, when a very poorly clad lady enters, accompanied by a beautiful little boy and girl, with the intention of asking aid from the jeweler. The woman becomes suddenly ill and falls fainting to the floor. She is beyond medical aid, and dies later in Abraham's home over the jewelry store, after telling her benefactor to write to her brother, Henry Morton, in England, advising him where the children are. The children are well taken care of at the jeweler's home with the able assistance of the daughter's lover, Nathan, who helps amuse and teach them. Before the arrival of the uncle serious trouble starts for Mr. Abrahams, who has patented a time lock.
