We follow store manager Dior preparing for the move to a new 15-million-pound shop, the creation of a new Percy Pig product that the marketing team are hoping will rescue the little-known beauty department, and the daring and bold new women's autumn clothing range launched after years of fighting bad reviews and poor sales.

The episode highlights M&S’s substantial investment of nearly half a billion pounds in 2023, focused on new store ventures. The largest of these new stores is situated in the Lakeside Shopping Centre, but there’s a race against time to get it ready for the holiday season, particularly for Christmas shoppers. The episode also follows the journey of product developer Abbie, who is working to bring a new and innovative twist to traditional classic biscuits. Her efforts to revolutionize the biscuit market by introducing new variations are explored.
