It's been three years since the BBC documentary crew first arrived at the office. Back for one last visit, they find Gareth Keenan now in charge and is running the office with a military precision. Since we last saw David Brent he has become a sales rep for a cleaning products company, released his own pop single and has acquired an agent to look after his celebrity appearances. He visits his old workplace regularly, despite him successfully suing Wernham Hogg for unfair dismissal. The big news for Tim is the imminent arrival of Dawn. The documentary crew has kindly offered to fly Dawn and boyfriend Lee from Florida back to Slough for the office Christmas party.
