LV spends all her time in her room listening to her dead father's record collection at full blast. She hardly ever speaks (even when directly spoken to). Her overbearing mother takes everything LV does as a personal slight.
Two men look set to change all that: There's the shy telephone engineer who notices LV and wants to get to know her better. There is also her mother's latest boyfriend who happens to be a small time promoter. After an accident with the electrical system, Ray notices the talent LV has and realises the money he could make if he could get the shy girl to sing on stage.
At the end of the day, the film is a coming of age drama which shows LV as she grows out of her shell. The characters are well drawn and believable. The setting, working class Northern England, adds to the feeling of bleakness in LV's life.
I confess that I'm not that big a fan of the coming of age genre. Having the main part given to someone who is clearly not an adolescent (even though she lives in the past) at the start is refreshing. I found the film compelling whilst watching it but, after it finished, was slightly disappointed.
