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 discovers that turning on the charm at work boosts sales but brings a new headache for her to deal with, along with running the world's worst choir.
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.
Ruby decides that running the choir is becoming too much of a hassle but stepping down now proves harder than she realised, especially now she's heard Western Windows perform.
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.
