A musical drama set in a small North of England town follows the lives of a small church choir. Choir Master Michael's crush on the choir's new soprano Layla, and his own musical ambition, drive him to blow up his marriage with Esther and consequently divides the choir in half. While Michael continues to master the original choir singing more traditional songs, Esther and her two sons set up a new choir called 'All the Small Things' with the help of the church's new curate Jake.
Jake takes a strong liking to Esther and as the series continues we see this attraction blossom. The new choir, 'All the Small Things' take on a much more modern approach to music and sing songs by famous band Blink182, such as 'What's My Age Again?' much to the original choir's horror; they sing more conventional songs. The series follows the lives of the people in both choirs as they compete with each other in professional competitions and as new relationships are formed between characters.
