In the 1970’s, they were the most popular sports stars on TV, a bigger draw than Major League Baseball. And then, virtually overnight, they disappeared — until now.

JAM is the story of the American Roller Derby League, a group of veteran Roller Derby stars now in their 50’s that are determined to make a comeback.

For seven years, award-winning filmmaker Mark Woollen chronicles league owner Tim Patten as he pours his heart and entire life savings into a revival of this uniquely American entertainment. JAM takes you on an epic journey filled with unimaginable drama, bitter rivalries, heart pounding action and an incredible cast of characters you’ll never forget. Hilarious, heartbreaking, inspiring, JAM is an amazing story about the lengths people will go to achieve their dreams.
