Alienated from an emotionally cold, conventional upbringing, a young woman named Tina moves to West Berlin and becomes entangled in the local gambling and red-light scene. To fund her growing alcohol and gambling addiction, she enters sex work and redefines herself as Lady MacLaine, building a decades-long career as a professional dominatrix in the BDSM subculture. The film weaves two distinct threads: direct documentary interviews with the real-life Lady MacLaine reflecting with humor, candor, and vulnerability on her work and client relationships, alongside stylized dramatized scenes featuring actors who reenact pivotal moments of her turbulent past.
