Bearded tells the story of Bet, whose father is a conservative political candidate, and Ace, her best friend, as they navigate family expectations, societal scrutiny, and the courage to be themselves. Set against a backdrop of fierce public debate in the midst of Australia's 2017 marriage equality plebiscite, this musical explores the intimate, private struggles of two young people caught in the middle, each grappling with their identities in a world that demands they choose between loyalty and self-expression.
