The University of North Carolina women’s soccer team is arguably the most dominant dynasty in college sports history. The program, under legendary coach Anson Dorrance, has won 21 national championships in the past 40 years and reached the final another five times.

Now, their story will be told in a one-hour original documentary, Hidden Dynasty: The Story of Carolina Women’s Soccer. The film, produced by Emmy and Peabody Award winner Ross Greenburg, will by premier on ACC Network as part of ESPN’s Fifty/50 initiative on Thursday, June 23 — the 50th anniversary of the landmark Title XI law.

The Tar Heels program built by Dorrance provided the foundation for the US Women’s National Team for decades, producing World Cup stars such as Mia Hamm, Kristine Lilly, Tobin Heath, and Heather O’Reilly, among many others.
