Mary takes on a struggling London bakery in a battle that ends in tears when she encounters one of the feistiest shopkeepers yet. Maher and Sons has been in business for 36 years but profits have halved in the previous five.

Mary tackles Chris and Juliet, a London couple who are running a beautiful Dorset village shop into the ground. The couple bought Clealls of Corfe Castle a year ago, but are haemorrhaging almost 6,000 pounds a month and now stand to lose their savings, their pension and their home. The shop is more mini-mart than country store, and the locals and tourists are heading for the hills.

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.

Mary battles to save a Kingston homeware shop living on borrowed time. Their 1970s stock is shockingly bad, the hippy owners are from another planet, and it may be almost impossible to bring them back down to earth.

Mary takes on an 80s hairdressing legend whose business is facing the chop. She is in Rochdale, one of the cities worst hit during the recession, and on the edge of town is the once-great John Peers hair salon, now teetering on the edge of oblivion.

Mary tries to fix a broken down Surrey DIY store - but the owner seems to have a screw loose! He's seems to have forgotten the nuts and bolts of his business, and it's up to Mary to hammer home some sense.
