Mary Portas, Queen of Shops | Fosters | 115-year-old greengrocers in trouble?

Mary focuses upon the most endangered sector of all - greengrocers. She finds a store in Merseyside on its knees, and takes on three fiery sisters that are running it into the ground. Fosters has been open 115 years, but the sisters who recently bought it are clueless, prickly and think they know best. Half the UK's independent greengrocers have closed in the last decade, and Fosters looks set to go the same way without a complete overhaul.

Mary has some big ideas to reinvent the store and the service it offers, but is met with scepticism and disagreement, and the sisters begin to fall out even amongst themselves. But unless they're willing to put in the commitment and hard work needed, it'll be impossible to rescue this sad little store.
