Cathy Lane, teen-aged daughter of a globe-trotting journalist, comes to live at the home of her uncle, a newspaper editor in New York City. Curiously, Cathy is the spitting image of her uncle's daughter, Patty. Appearances aside, however, the urbane Cathy is nothing like her cousin Patty, who is the typical American teenager.
