The first programme meets Manchester sewer workers Mick and Shaun, who have first-hand knowledge of the public's poor diet; event cleaner Marcia, who gives an insight into how Brits behave in a crowd; and window cleaner Ross, whose job involves keeping a huge national icon absolutely spotless. Plus, pest controller Jim battles an infestation of bedbugs.
