Charlotte Marlin was raised on a Connecticut farm in the shadow of Micah's apple tree, whose fruit, according to legend, changed from pale green to spotted red after a peddler was killed and buried at its base. Orphaned, Charlotte goes to live with her aunt and pretty cousin Margaret. She meets Neil Kennedy, a poor boy who is working his way through college, and they become friends. Margaret, who is engaged to wealthy Willis Hayland, teases Charlotte, who considers herself to be plain-looking. At high school graduation Charlotte's academic achievements are obscured by Margaret's leading role in the school play. Jealous of Margaret, Charlotte resolves to make everybody like her, to be famous, and to marry a millionaire. She learns that to make everybody like her, she must be friendly to everyone. To become famous, Charlotte becomes a golfer and wins the world's championship tournament. She nurses millionaire Perry Graham after hitting him in the head with a golf ball, supposedly an accident, but when Perry falls in love with her, Charlotte realizes that she loves Neil, who has become a promising physician.
