Valco finally announces its new area manager while new sales rep Duncan ruffles a few feathers. Gavin's thoughts turn to the amount of cheap unhealthy food that Valco sells.

New area manager Cheryl struggles to keep a lid on her private life whilst she also has to focus on leading a meeting to all the Valco managers she is now in charge of in the area. Meanwhile, Neville is brimming with confidence when he helps new shelf-stacker Shai.

It's a big day for Gavin as he prepares to launch his new healthy eating initiative. Meanwhile, Brian gives a harrowing presentation on the dangers of fat.

It's Gavin and Cheryl's 11-month anniversary so Gavin plans a romantic afternoon. But when Duncan catches wind of their plans he starts to meddle with plans of his own.

Duncan takes great delight in announcing the failure of Gavin's health food drive by spreading rumours across the shop floor. Meanwhile, Neville is roped into giving Linda driving lessons.

Cheryl orders Gavin to cooperate with Duncan as he launches a new energy drink in store. Meanwhile, things between Holly, Katie and Daniel take an unusual turn.

It's Christmas Eve and Gavin has an important proposal for Cheryl, but when a bid to throw her off the scent spectacularly backfires, he is left desperate to make amends. Brian returns to the store and is clearly unimpressed with humble new pharmacist Alan, while Colin and Lisa witness something horrifying and the spark between Katie and Daniel becomes clearer than ever at the Valco Christmas party.

It's Christmas Eve but all is not well. A hapless team of criminals are planning to nick the takings: can Gavin save the day?
