Choirmaster Gareth Malone tries to create a choir at a boys' school in Leicester to perform at the Royal Albert Hall. After their first performance at the school summer show, Gareth is ready to take his choir to the Albert Hall. To get there, his boys must convince singing expert Leonara Davies that they're good enough. Gareth also decides its time his boys learnt to sing classical music - in ancient Italian. But when the new term begins, he finds over half of his choirboys have deserted him.
