In this funny tale of deception and romantic fireworks, a rather prissy New England school marm finally gets a chance to achieve her dream and become a commercial artist when she is hired to illustrate the beloved "Uncle Bump's" latest children's book. She adores Bump's earlier works and is anxious to meet this gentle fellow in New York. Imagine her shock to discover that Bump is actually a boozy, cynical, young man who despises all children. Appalled, she decides to expose him as a fraud. The author's publisher nearly goes bazinga when he thinks of all the money to be lost and so tells the teacher a whopper about how the writer became bitter after his wife died and left him with a troublesome son. This melts the teacher's heart and she decides to help out. But first she wants to speak to the boy. In desperation, the publisher pays a tough, wiseacre urchin to impersonate the nonexistent son. This tough little cookie helps to bring the two opponents closer and love blooms until she learns the truth. Broken-hearted and angry, the teacher returns to New England to marry an old beau. Fortunately, the cagey orphan, who has come to love them both, has a few aces up his sleeve and insures that the two are reunited. A happy family is born and romantic bliss ensues.
