Loads of new employees have their first day at Valco. Colin is shocked when his nan, Rose is amongst the newbies. Rose makes her and Gavin's life a misery when she meddles in management matters. Pharmacist, Brian takes on a unlikely sidekick, in Margaret.

While salvation arrives for Gavin in the form of new assistant manager Daniel, sparks fly when VIP till girl Charlie also hits Valco. Charlie isn't the brightest spark in the cereal box, but she'll probably keep her job because her dad happens to own the supermarket empire. Somebody should mention that to Daniel before he makes a drastic decision he'll regret.

Some fake banknotes are doing the rounds and eager-to-please Rose shops a customer for the crime. His notes turn out to be fine, but the OAP won't let a teeny tiny detail like innocence stop her from administering her own unique form of justice. Could it cost Rose her job, though? Brian, on the other hand, has a bee in his bonnet about a parking space.

First aid training gets under way but Brian is skeptical about such matters; pharmacists rule medicine, you see, not Jonny-come-latelies. Security guard Ian, meanwhile, is at his wits' end because of an unwelcome visitor: a fox. He'd appreciate it, then, if Harry (and his collection of fake fur coats) would stop winding him up.

Rose and Margaret realise they know each other from the past and that Margaret won Alan's heart at the time. Brian is dumbfounded when Colin abuses his homemade hangover cure. Gavin is distracted when a special guest is due to appear in store.

The canteen prices have been hiked up, meaning the staff aren't happy. Charlie pleases everyone when she takes the staff out for lunch, management isn't impressed though as they believe the staff have gone on strike. Rose and Lisa's feud boils over.

Charlie's dad Brendan stops by the store and Gavin is determined to make her look good, something that's easier said than done. Elsewhere, Linda's dirty secret is revealed, and, finally taking charge, Colin forces Rose and girlfriend Lisa to battle out their differences once and for all - in the back of a locked delivery van.

It's charity day at Valco and everyone's doing their little bit to help. Gavin has offered to shave his legs, Brian is dressing up as a giant paracetamol tablet, and Sue and Linda are hitting the saddle for a sponsored bike ride. There's a big prize draw to win a car, too, but fair play is called into question when Rose sets her sights on it.
