Siberia, 1953. For years, the seductive Comrade Colonel Ilsa was the commander of the Stalinist Gulag 14: a purgatory in the unforgiving Siberian tundra designed to rehabilitate political dissidents. In the wake of Iosif Stalin's execution, Ilsa's comrades burned the camp to the ground, determined to leave no one behind. The only survivor, Andrei Chikurin, escaped and vowed to expose the unspeakable horrors committed inside the impenetrable prison. More than two decades later, Ilsa now runs a profitable brothel in Montreal, unaware that Chikurin still thirsts for revenge. Will Ilsa, the Tigress of Siberia, ever pay for her crimes?
