The Dolans live by their wits, jumping freight trains and lining up for day work at crooked job agencies. While 16-year-old Rye yearns for a steady job and a home, his older brother, Gig, dreams of a better world, fighting alongside other union men for fair pay and decent treatment. Enter Ursula the Great, a vaudeville singer who performs with a live cougar and introduces the brothers to a far more dangerous creature: a mining magnate determined to keep his wealth and his hold on Ursula. Dubious of Gig’s idealism, Rye finds himself drawn to a fearless 19-year-old activist and feminist named Elizabeth Gurley Flynn. But a storm is coming, threatening to overwhelm them all, and Rye will be forced to decide where he stands.
