Czechoslovakia, October 1937. Vast crowds have gathered to watch the threatened nation's most prestigious sporting contest: the Grand Pardubice steeplechase. Notoriously dangerous, the race is considered the ultimate test of manhood and fighting spirit. The Nazis have sent their paramilitary elite-SS officers on a mission to crush the 'subhuman Slavs'. The local cavalry officers have no hope of stopping them. But there is one other contestant: a countess riding a little golden mare. . . The story of Lata Brandisová is by turns enigmatic and inspiring. Born into privilege, she spent much of her life in poverty. Modest and shy, she refused to accept the constraints society placed on her because of her gender. Instead, with quiet courage, she repeatedly achieved what others said was impossible and rose above scandal to become her nation's figurehead in its darkest hour.
