The documentary series delves into the nine years during which the rebellious ABA challenged the established NBA. It shows how this scrappy league laid the foundation for modern basketball and forever changed sports culture. The ABA introduced groundbreaking elements that are now indispensable, such as the three-pointer, the iconic red, white, and blue ball, and the first-ever Slam Dunk Contest. Where the NBA was rather rigid at the time, the ABA brought flair, speed, and creativity. The league gave players the freedom to express themselves and was more socially progressive and inclusive. The series features unique footage and interviews with icons such as Julius "Dr. J" Erving, George "The Iceman" Gervin, Moses Malone, and Rick Barry.
