Fed up with New York life, Susan Applegate heads home but finds herself short on train fare and poses as a 12-year-old to buy a half-price ticket. When she hides in a compartment with handsome Major Philip Kirby, he insists on taking little "Sue Sue" to his military academy after the train stalls. As Susan falls for Philip, she struggles to keep her secret before her clever ruse ends in scandal. © 1942 Universal Studios. All Rights Reserved.
