A womanizing music composer repeatedly antagonizes the other half of his party line when she complains of his constant telephone use. Mutual hatred ensues, though the two had never previously met. Later, he manipulates her into falling in love with him by adopting the persona of a Southern Gentleman and playing this personality off of his own in a series of occasionally tag-team "three way" party line conversations. She later discovers his deception and is outraged. The film ends (hilariously) with him breaking down her front door and dragging her screaming out of bed through downtown New York, past a police officer, and finally up the stairs to his apartment where everything is made all right again by his condescension to marry her. A delightfully charming piece of Americana.
