Tischa "The Tigress" Thomas has a clear goal: she wants to take the title as the best female bodybuilder in the world. With her 17-inch biceps and enormous back muscles, she is a strong yet highly sensitive person who fights self-doubt and social discrimination and longs to be accepted by others for her own sake. Tischa earns her living as a dominatrix, her most important partner being her 70-year-old roommate Eddie, who supports her in the competitions. But when she falls short of her dream of winning the title, a world comes crashing down for Tischa - and suddenly the question arises: is she ready for a life beyond the competition stages?
