The Major and the Minor

Susan Applegate, tired of New York after one year and 25 jobs, decides to return to her home town. Discovering she hasn't enough money for the train fare, Susan disguises herself as a 12-year-old and travels for half the price. Caught out by the conductors, she hides in the compartment of Major Philip Kirby, a military school instructor who takes the "child" under his wing.
