Pimm is a retired pub keeper, touring the US on a hospitality visit that's really a thinly disguised publicity stunt, and Derek, a college athlete and TV-commercial model chafing at the prospect of becoming a hot commercial property, is assigned to chauffeur him. The two are innocents abroad in a country where only money talks. Both disillusioned, Derek the ""unsubtle"" jock and the gentlemanly Mr. Pimm bolt the tour to see America on their own. . . and nearly don't get any farther than a West Virginia backcountry town where Derek is mistaken for a big-time scout and the local fathers turn mean in their disappointment. Dixon's idea is a good deal bolder than its execution. At times his Mr. Pimm (the name itself an invention of the makers of Pimm's Cup, a gin cocktail) seems destined to be the vehicle for picaresque satire, but that Derek is able to resolve his problems simply by saying no to a pro contract and going off to work with underprivileged kids certainly softens up the picture of pervasive, big-business decadence. Despite frequent lapses into sentimentality and Dixon's unaccountable faith in a hero who too often comes across as shallow, Pimm's Cup is just subversively effervescent enough to serve as a bracing pick-me-up.
