The middle-class Baxter family enjoys a comfortable and placid life until the summer when their neighbors, the Parcher family, play host to an out-of-town visitor, Lola Pratt. An aspiring actress, Lola is a "howling belle of eighteen" who talks baby-talk "even at breakfast" and holds the center of attention wherever she goes. She instantly captivates William with her beauty, her flirtatious manner, and her ever-present prop, a tiny white lap dog, Flopit. William is sure he has found True Love at Last. Like the other youths of his circle, he spends the summer pursuing Lola at picnics, dances and evening parties, inadvertently making himself obnoxious to his family and friends. They, in turn, constantly embarrass and humiliate him as they do not share his exalted opinion of his "babytalk lady".
