A casual comedy, this revolves around the nephew and heir apparent of the stuffy head of an English postal educational (correspondence) school whose dedication to the business is short circuited by a French girl who stows away on the Hirondelle, a luxury yacht his uncle has hired. The passengers are of the school's faculty, a special guest is M. Morand whose continental Institut Ashley is determined to buy, and the officers and crew are all devoted to artistic pursuits. In this all male world Felicie's charms are focused on David Seldon -- she interrupts his planned schedule, she is a partner in studying Morand's course in courtship, and she is the instigator of escapades which create awkward situations for David. Uncle Ashley has his means of getting into trouble too so that, having cruised along the coast of Cannes, attended the International Federation of Correspondence Schools in Barcelona- it is time for the denouement of Felicie's identity -- and her capture of David. Frothy fun.
