Sparkling wit with a Shakespearean twist. Walking home at dawn, quite drunk, Sir Richard Wyndham encounters heiress Penelope Creed climbing out her window. She is running away from a dreaded marriage to her fish-lipped cousin, while Sir Richard himself is contemplating a loveless marriage with a woman his friends have compared to a cold poultice. Sir Richard can't allow her to careen about the countryside unchaperoned, even in the guise of a boy, so he pretends to be her tutor and takes her on a fine adventure. When their stagecoach overturns, they find themselves embroiled with thieves, at the center of a murder investigation, and finally, in love.
