Directed by Nikolay Khomeriki, this gritty Russian historical drama series is set in 1903 St. Petersburg. The plot centers on Kseniya (Ksusha) and Stesha, two young women trapped in an underground "house of tolerance" (a high-end, secret brothel). Run by a highly respectable yet completely ruthless madman/madam controller, the girls are forced into prostitution, selling an illusion of love and luxury to elite clients. Beneath the surface glamour and absolute subjugation, the narrative follows their inner resilience, dark survival tactics, and desperate spiritual yearn to break free from the inescapable criminal ring at any cost.
