School documentaries seem to be all the rage this September and tonight we're off to Harrow, one of the most famous schools in the United Kingdom: Winston Churchill and Benedict Cumberbatch were educated in its hallowed halls don'cha know? Filmed over the course of a year, the programme aims to explore some of the oddest traditions of the public school. In this first episode we're meeting a selection of students who are leaving their families behind to take up residence at the school, and get used to life in blazers.
