What would you do if your parents gave you away to a circus? 'Marvellous Miss May' is the inspiring true story of a tiny circus performer, whose mother was too poor to keep her. In November 1901, May's desperate mother gave her little girl to Wirth Brothers Circus. May missed her family terribly. It was hard for the seven-year-old to settle into a circus where she knew nobody! But this young girl from Bundaberg in Queensland had big dreams: she wanted to become the greatest equestrienne in the world, performing astounding tricks on the back of a galloping horse. After years of working hard to perfect her circus skills, Miss May Wirth, as she was now called, was allowed to train as a bareback rider - one of the most difficult and dangerous jobs in the circus. Would May's agility, flexibility, poise, talent and determination enable her to fulfil her dreams?
