The couple move to Paris, where Panthea meets a Russian nobleman who knew her in her mother country and who has a powerful influence in musical circles. Panthea's husband becomes desperately ill through the failure to secure a hearing for his opera and the physicians express their belief that unless the boy's ambition is speedily realized there can be no cure.
