Mary visits Hallmark Foods, a local convenience store near Slough that's losing money and customers, and she is shocked to see how some members of staff are behaving.

Mary heads to the Suffolk seaside town of Lowestoft to work with Godfreys, a huge family-run department store with a shocking overdraft and its future in doubt.

Mary Portas heads to south-east London, and London Fashion Week, to help Gemma get her struggling clothes boutique Diosa back on track selling urban fashion to young women.

Mary takes on a struggling car dealership in Aylesbury, urging the blokes who run it to undergo a culture change to appeal equally to women and men.
