The search for the new Valco area manager is finally over. After an unexpected incident in the store, Gavin's thoughts turn to the amount of cheap unhealthy food that Valco sells; and pushy, arrogant new 'pleasure food' sales rep Duncan Trench makes his presence felt.

New area manager Cheryl struggles to keep a lid on her private life, while 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.

Duncan's back in store and is far from impressed with Gavin's health food drive. Katie also faces an unwanted visitor in the form of Daniel's girlfriend Holly.

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.

Duncan takes great delight in announcing the failure of Gavin's health food drive, while 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.
