It surely was a defining moment. Perhaps even the biggest moment in the history U.S. women’s sports.

The U.S. women’s soccer team took the country by storm in 1999. It all culminated in a packed Rose Bowl for the World Cup final against China.

Their story, The 99ers, is the latest Nine for IX documentary. It airs tonight on ESPN at 8 p.m. ET. Official rundown below.

Here’s the rundown:

The world of women’s sports was kicked upside down on July 10, 1999. Before a sold-out crowd of more than 90,000 at the Rose Bowl and an estimated 40 million Americans watching on television, the U.S. women’s soccer team reached a cultural and athletic pinnacle with its penalty-kick shootout victory against China to win the Women’s World Cup.

As told through the voice of a longtime team captain, Julie Foudy, we get an inside look at the strong team ethic and rare “do for each other” mentality that propelled the squad to victory that summer and turned it into a cultural touchstone.

With unprecedented access, The 99ers uses candid, behind-the-scenes footage shot by the players themselves during the three-week tournament to present a unique portrait of the women who irrevocably changed the face of women’s athletics. The film reunites key players from the 1999 squad and also talks with current U.S. players to examine how women’s soccer, and women’s sports as a whole, has changed since that epic day at the Rose Bowl.

Foudy: A friend recently asked me how I would describe the experience of the 1999 World Cup to my young kids and, without hesitation, the first thing that came to mind was: BEST. JOB. EVER. Yes, almost two decades of playing for my country alongside an amazing group of women who taught me the value of competing, growing and digging deeper than I thought possible counts me among the lucky. But, more important, this group of women showed me that challenges, obstacles and adversity are really just thrilling, laughter-infused adventures that are part of the wonderful journey.

It all came together one sweet summer in 1999. And no one has ever seen it from the inside. Given our propensity for the absurd, I thought it would be fun to document our 1999 World Cup experience on a camera. So with no plans and no shooting experience, I just kept pressing record … so much so that Mia eloquently declared the camera a “great big zit on my heeeed” in her best Scottish accent.

We have compiled the best of many hours of my personal footage and have used these moments as a launch pad to discuss that summer — the impact, the legacy and the question that has trailed us all for a decade: are we pioneers or was 1999 just an anomaly? This film is a completely unique look back, from the gals who gleefully shimmied through that summer to providing a glimpse into the personalities, pressure, excitement and growing recognition that the summer would be one to remember. But consider yourself warned: there will be a lot of bad hair, bad dancing, bad singing, and even some nudity, thanks to Brandi Chastain.
