A person dressed as Santa Claus opening a door.

The ad opens with a person dressed as Santa Claus opening a wooden door. The person then walks into a room and sits on a couch next to someone dressed as a Christmas tree. They are both wearing festive attire and sitting in a decorated living room. The Santa figure then eats a mince pie. The ad then cuts to a close-up of two mince pies on a plate, one of which is broken open to reveal the filling. The Waitrose logo appears on screen.
