Duke Turnbeau (David Soul) has come to England, in the 1930s, as a way to improve his fortunes. For some reason, he believes that his larcenous ways will bring him prosperity in the country which at one time or another has had rulership over a large portion of the globe. While there, he meets Rosie McCratchit (Pamela McMyler), a lovely Irish gal who could do with some improvement in her fortunes as well. Together, they have a series of legal, quasi-legal and definitely illegal adventures, including Duke's cow-roping and Rosie's response to the mud-wrestling challenge of the Amazon Lady, as well as an attempted armored-car robbery.

A man with learning difficulties suffers neglect and ill-treatment, and this is only exasperated when his parents die and nobody seems to know what to do with him. A sequel to this film, titled "Walter and June", was released in 1983 and set 19 years later in time. In the United States, these two are sometimes bundled together under the title "Loving Walter".
