The show follows a fictional man simply called 'Fonejacker', played by actor Kayvan Novak, who is a masked prank caller who calls unsuspecting members of the public as various characters, accompanied by on-screen animations, consisting of pictures of people with their mouths moving, in a similar style to Monty Python animations. Others are accompanied by undercover filming in which the Fonejacker is in a street calling a company nearby. He is always seen wearing a red and white bobble hat (black in the Pilot) and sunglasses. Whilst Kayvan Novak's appearence is not seen as Fonejacker, he appears during Mr. Doovd's calls as a model advertising various items including DVD players and for DFS.
