　　Noel Fielding stars as Dick Turpin, who always believed he was destined for something bigger than a life chopping meat in his dad's butcher's shop. And he was right. When he inadvertently becomes leader of the Essex Gang, a notorious bunch of outlaws, he realises he's found his calling. Sure, he might be a peace-loving vegan who believes in panache over pistols, but what he lacks in hard-core highway skills he makes up for in imagination, invention and incredibly pointy purple shoes.
　　In this irreverent retelling, Dick is the most famous, but least likely of highway robbers, whose success is defined mostly by his charm, showmanship and great hair. Together with his gang of loveable rogues, Dick rides the highs and lows of celebrity - and does what he can to escape the clutches of the Thief Taker General.
