Choirmaster Gareth Malone tries to start a choir at a boys' school in Leicester to perform at the Royal Albert Hall. After two terms, Gareth has created a 100 part boys' choir and put singing back into school life. He has even ingratiated himself with the playground rap crew. But disaster strikes when the choir's new soloist gets a throat infection. Gareth takes everyone for some last-minute inspiration - a rehearsal with the Kings' College Choir in Cambridge.
