Choirmaster Gareth Malone has already set up two of the four workplace choirs that will compete in his singing contest, at Lewisham Hospital in London and at the Royal Mail in Bristol. This time he travels to Manchester to create his third choir amongst baggage handlers, security staff, air traffic control and the fire crew of Manchester Airport. With the staff more used to singing karaoke than choral music, things get off to a bumpy start but, as Gareth begins his search for a soloist, he discovers hidden talent in unexpected places and the choir is soon ready for take off.
