Dysfunctional family sitcom Such Brave Girls follows sisters Josie (Kat Sadler) and Billie (played by Kat’s real-life sister, Lizzie Davidson) and their single mother Deb (Louise Brealey) navigating life armed with nothing but poor judgement and self-esteem exclusively tied to people who couldn't care less about them. They're vain, selfish, heavily in debt, pathologically desperate for affection and bursting with misplaced, terrifying love.
