In a quiet house, Beth Thornton - burnt out and on the brink - prepares to end it all, when an unexpected phone call changes everything. Jess Burchill assembles an unlikely crew of sassy women to form a punk rock band for a local talent contest. Holly Gaskell, a police officer, arrests chaotic Kitty Eckersley, who might just prove to be the missing ingredient the band - and suicidal Beth - needs.

Struggling to process the shock of her discovery, Kitty teeters on the verge on a nervous breakdown. Jess writes one song about ungrateful children, Yvonne writes another about the traumas of giving birth, and Holly's promising date turns into an excruciating encounter in the bedroom. Kitty's discovery leads to an explosive Sunday lunch round at Beth's house.
