David Mitchell sets out on a vigorous but impeccably polite investigation into the confusing world of manners. Are they really in decline, as many would have us believe? Or are we just throwing off the shackles of the Victorian obsession with etiquette?

Over the course of the series, David eats his lunchtime sandwiches with children in a primary school, and later goes to a street market to see manners - good and bad - in action. He explores where our manners come from with Professors Steven Pinker from Harvard University and the author Henry Hitchings. What do we mean by 'civility' and 'good manners' in public places? Why are people still pinching vicars' bottoms, and what can the state do to improve standards of public behaviour? And, David asks, how is the digital age changing our sense of public space?
