In order to escape the wrath of Honoria Glossop and Aunt Agatha, Jeeves and Bertie board an oceanliner heading for New York. Unfortunately, Bertie is landed with the task of looking after Wilmot Malvern, a lad long cooped up with his mother Lady Malvern. He turns out to be a limpet of the worst sort with the knack for clinging to Woosters. On the ship Bertie also runs into Tuppy, who's off to America to become an importer of cars to Britain. Once in New York, the mother's boy breaks loose onto the nightclub scene with disasterous results, and Tuppy meets with similar lack of success when he realises he'll have to buy more than one car at a time and that the steering wheel's on the wrong side.
