This groundbreaking documentary dismantles one of society's most persistent myths piece by piece. Journeying from the bones of prehistoric women who were stronger than today's elite athletes, to the finish lines of grueling ultramarathons where women consistently outperform men, the film uncovers a hidden story of biological superiority. Through startling scientific evidence and expert testimony, it reveals that the true measure of strength isn't found in a single burst of power, but in resilience, metabolic efficiency, and the profound, cellular ability to survive. Prepare to have your reality rewritten; this is the untold story of the ultimate endurance machine.
