Some fights are bigger than belts. Countdown: Taylor vs. Serrano, a new Netflix documentary, gives boxing fans an intimate look at the journey toward one of the most important bouts in women’s boxing history — and the all-women’s fight card it headlines, streaming live from Madison Square Garden on July 11. The documentary tracks the journey of two undisputed champions: Ireland’s champion Katie Taylor and Brooklyn’s Puerto Rican powerhouse Amanda Serrano. 

Directed by Jackie Decker and Tim Mullen, and narrated by Uma Thurman, the film follows the intense final stretch leading up to the July 11 trilogy fight. Produced by Most Valuable Promotions and distributed by Netflix, Countdown offers an inside look at both fighters’ mental, emotional, and physical preparations. The documentary goes beyond the training montages to explore the legacy stakes, personal sacrifices, and unshakable rivalry that make this bout one of the most anticipated fights in women’s boxing history.

For Serrano, it’s more than just a shot at redemption — it’s the next chapter in a career that’s already transformed boxing history.

Who is Amanda Serrano? Read more on her bio, record, and titles

Amanda “The Real Deal” Serrano is one of the most decorated fighters — male or female — to ever lace up a pair of gloves. Born in 1988 in Carolina, Puerto Rico, and raised in Brooklyn, Serrano grew up in a boxing household and drew early inspiration from her older sister, Cindy, a former professional boxer who held the WBO female featherweight title from 2016 to 2017. At 18, Amanda started sparring in earnest — and quickly proved she was built for the fight game.

After a dominant amateur run, Serrano turned pro in 2009 and claimed her first world title just two years later, winning the IBF super featherweight championship in 2011. She soon became known for her knockout power, relentless volume, and ability to move between divisions. Serrano has captured world titles across seven different weight classes — a unprecedented feat recognized by Guinness World Records.

And she wasn’t content to stop there. In 2019, she defeated Heather Hardy to reclaim the WBO featherweight belt — and hasn’t let it go since. In 2021, she added the WBC and IBO titles with a thunderous knockout of Daniela Romina Bermúdez in Puerto Rico. In the years that followed, she unified the division by winning the IBF from Sarah Mahfoud and the WBA from Erika Cruz, becoming the undisputed featherweight world champion in early 2023.

Serrano is a fighter who’s also changed the system from within. The same year she won the WBA, she headlined the first women’s unified world championship to break from the official 10 two-minute rounds for women’s title rounds. For the first time, it was fought under 12 three-minute rounds — the same format as men’s title fights. Serrano threw 1,103 punches in that bout against Danila Ramos, unleashing a pace and performance that underscored both her conditioning and her commitment to equality in the sport.

In December 2023, Serrano voluntarily vacated her WBC title after the organization refused to sanction 12x3–round bouts for women. “I’m keeping my commitment to change boxing,” she said at the time, emphasizing her decision to fight only 12 three-minute rounds. “Moving forward, if a sanctioning body doesn't want to give me and my fellow fighters the choice to fight the same as the men, then I will not be fighting for that sanctioning body.” But now, with the Countdown cameras rolling, she’s making one exception: stepping back into the ring to settle the score with Taylor.

How the Taylor vs. Serrano rivalry began

Serrano and Taylor initially met in 2022 at New York City’s Madison Square Garden, headlining the venue’s first-ever women’s boxing main event in a fight that lived up to — and exceeded — the hype. Their bout was named Sports Illustrated’s Fight of the Year and The Ring’s Event of the Year, and it delivered historic paydays and seismic attention to the women’s game. Taylor edged out Serrano in a razor-close split decision that still sparks debate.

Amanda Serrano’s last fight on Netflix: What happened during Paul vs. Tyson?

When Amanda Serrano stepped into the ring for her long-awaited rematch with Katie Taylor on Nov. 15, 2024 — co-headlining the blockbuster Paul vs. Tyson card at AT&T Stadium — she brought the pressure from the opening bell. Over 10 rounds, Serrano outthrew and outlanded Taylor, unleashing a ferocious 324 punches to Taylor’s 217. But her relentless pace and aggressive style wasn’t enough to sway the judges. All three scorecards read 95–94 in favor of Taylor, who retained her undisputed super lightweight titles by unanimous decision in what instantly became one of the year’s most debated outcomes.

The bout turned especially contentious in Round 8, when Taylor was docked a point for an accidental headbutt that opened a deep cut above Serrano’s eye — a cut caused by heads colliding in Round 4. Blood streamed down her face in the final rounds, but Serrano persevered — pushing forward, trading combinations, and refusing to let the cut derail her momentum. Post-fight, she accused Taylor of intentional repeated headbutts, saying, “She [headbutts] in every fight … no matter how many cuts I get, in my face, I’m going to die to the very end.” 

The fight also skyrocketed Serrano into pop culture consciousness: She earned over a million followers on social media, making her the most followed female boxer in the world and cementing her status as a global icon. 

And on July 11, she’ll face Taylor one more time.
