The daughter of immigrants who fled the Irish Potato Famine, Rose Meehan longs for a better life than the tenements of New York City. Courted by two men—a young doctor who represents material security, and a poor violin instructor who has captured her heart—she must choose between a life of advantage-grabbing or a life of faith. When Manhattan explodes in mob rule following Lincoln's unpopular draft, the heroic action of one suitor brings provision for those she loves, and reveals God's plan.
