Joe (Conrad Nelson) is a mouthy Scouse, living in posh Highgate. His six-year-old daughter Megan (Lauren Mote) urges him to do what Mum says and be nicer to the neighbours. So he tries. But, oh dear, Megan goes out to play and chalks a great big picture on the pavement. Joe says it's like Guernica. The neighbour whose house it's in front of doesn't see it that way, refers it upward to the man who's in charge of the residents' association. Out of Megan's chalky drawing rise great clouds of paranoia. Jeff Young's comedy grinds a sparky social axe.
