Nina Anisimova was one of Russia's most renowned ballerinas and one of the first Soviet female choreographers.

Yet few knew that her exemplary career concealed a dark secret. In 1938, at the height of Stalin's Great Terror, Nina was arrested by the secret police, accused of being a Nazi spy and sentenced to forced labour in a camp in Kazakhstan. Trapped without hope - and without winter clothes in temperatures of minus 40 degrees - her art was her salvation, giving her a reason to fight for her life.

As Nina struggled to survive in the Gulag, her husband fought for her release in Leningrad. Against all odds, she was ultimately freed and astonishingly managed to return to her former life, just as war broke out. Despite wartime deprivation and the suffocating grip of Stalin's totalitarian state, Nina's irrepressible determination set her on the path to become an icon of the Kirov Ballet.

A remarkable true story of suffering and injustice, of courage, resilience and triumph.
