Helen: Believe

At just 23-years-old, Helen Maroulis heads to Rio de Janeiro, Brazil, for her first Olympic Games. She competes against Saori Yoshida, 13-time World Champion and the most decorated wrestler of all time. Yoshida has been undefeated for over four straight years, until Maroulis shocks the world and becomes the first, and only, American woman to win a gold medal in wrestling.
