"Such Brave Girls" is a British sitcom created by Kat Sadler, who also stars as Josie Johnson. The series follows Josie, her sister Billie (played by Sadler's real-life sister Lizzie Davidson), and their single mother Deb (Louise Brealey) as they navigate life's challenges armed with poor judgment and self-esteem tied to indifferent individuals. The show delves into themes of family dysfunction, mental health, and the pursuit of affection, all portrayed with a darkly comedic lens.
