Choirmaster Gareth Malone goes to a town called South Oxhey in Hertfordshire, which has no tradition of singing, and little cultural activity. Gareth makes it his mission to make South Oxhey a centre of true choral excellence. This time, Gareth has a new set of challenges and has to convince adults with longer-held and deeper prejudices about choirs that they should be singing alongside him. Gareth takes his choirs through an extraordinary set of challenges and a fascinating set of local characters emerges to become deeply engaged in his choral project. His final challenge is to put on a major performance in South Oxhey itself, and invite the whole town to the party.
