Mary Bligh is no shrinking violet. After an horrific six-month sea voyage from Britain, she proves to be as strong-willed as her father, the bloody-minded, newly appointed Governor William Bligh. The pair immediately scandalise Sydney with their personalities, his politics and her pantaloons.

And when 300 armed soldiers of the Rum Rebellion march on Government House to depose him, the Governor is nowhere to be seen as Mary stands defiantly at the gates, fighting them back with just her parasol.

Despite being bullied, belittled and betrayed, Mary remains steadfast, even when her desperate father double-crosses her yet again in his last-ditch attempt to cling onto power. But will Mary turn out to be her father's daughter and deceive him in pursuit of her own dreams and ambitions?
