At Hellocom, a Bristol call centre, fun and irreverent Ruby tries to put a smile on her colleagues' faces, dodge getting the sack, and run a choir that she'd much sooner avoid.
Ruby decides to sort everyone else's life out, from Cameron's commute crush to Melon's birthday party. After all, anything is better than fixing her own mess.
It's the final of ChoirFest SouthWest and Ruby's forced to decide if she can put the happiness of her team ahead of her overwhelming desire to self-sabotage.
