British choirmaster Gareth Malone believes that choral singing is a way to bring together people to work together toward common goals. As such, he travels across the United States looking for fractured community groups, organizations, and communities themselves that he feels need to be brought closer together for whatever reason. In one week's time with each of these, he will recruit people to join a choir, learn two choral arrangements of songs which features soloists from among the group, and perform those two songs to an audience. These groups may not on the surface be natural fits with choral singing, which may make the process that much more difficult for him. Through this process, Gareth not only wants to bring the people closer together, but also help certain individuals within the group who may be facing personal issues.
