After preaching at a camp revival meeting that charity begins in the home, Littleton minister Hamilton Gregory finds a girl calling herself only Fran on his doorstep and takes her into his home. Fran soon finds that Mrs. Gregory is unhappy because Gregory has no affection for her, preferring instead his secretary Grace Noir. When Fran admits to Gregory that she is his daughter by an abandoned woman, and attempts to have him get rid of Grace, Grace has Bob Clinton make inquiries concerning Fran's past. When the circus comes to town, Fran, in disguise, substitutes for an ill lion tamer, because the circus is her hidden background. Seeing her in danger, Gregory realizes his familial responsibilities and refuses Grace. Fran then marries the superintendent of her school.
