A young woman at a girl's school in Switzerland makes up stories about and writes herself letters from an imaginary explorer-adventurer father; and is eventually put in a position where she has to produce him. Interesting things happen as she talks a visiting Englishman into helping her out. 讲述Deanna Durbin饰演的Gloria Harkinson杜撰了自己有位父亲，误打误撞将Herbert Marshall饰演的Richard Todd / Mr. Harkinson（音乐家）冒认为父亲，出于善意和体谅，上演了一段以假乱真，皆大欢喜喜剧故事。
