Retail guru Mary Portas sets out to keep Britain's small shopkeepers in business by sharing the tricks of the trade with failing boutiques. Mary is in Doncaster to help turn around Homeboy, a boutique trying to sell menswear and womenswear to the party crowd. Owner Cath Taylor blames the arrival of a new shopping centre for the downturn in her fortunes. But with celebrity collections in large fashion retailers, Mary has got to give Homeboy an entirely new image if it's going to compete. A new name, new labels and a new shopfloor are all in the offing, but Cath’s partner and menswear manager, Jock, is not convinced Mary has the answers, and nearly blows the entire marketing campaign by ignoring Mary’s advice during a pitch to a national magazine.
