After an opening where we see boxer Linda "Lefty" Lumaban (Dana Vespoli) doing her locker-room prep for a fight—aides lacing and taping her gloves, a good-luck kiss from Alexis Texas—as voiceover sports commentators point out that she's undefeated and her coach (James Avalon) is a former middleweight champ who saw potential in the young boxer when he was a cop, Lefty struts to the ring, the crowd cheering ... and we flashback to her passionate bed bounce with Texas before signing the contract for the fight. Then, in the locker room, Lefty abruptly calls off the fight after the coach's unexpected death from a heart attack—an action explained in the next scene by dialogue between editor Jane Hamilton and reporter Bree Daniels. Bree wants to find Lefty and ask her about a fighter who just challenged her in retirement—the same boxer Lefty was going to fight when her coach died—and if Lefty knows about her legacy as a leader for women in combat sports.

Bree discusses Lefty while in bed with S.O. Julia Ann, who notes that Lefty was an out lesbian and had "a public long-term relationship with porn superstar Alexis Texas." Bree finds and interviews Texas about their relationship, and Texas flashes back to a three-way she had with A.J. Applegate and Dani Daniels while Lefty watched. After an argument with Julia Ann about her writing "hobby," Bree has a chat with Lefty's cut man/sparring partner that leads her to find Lefty, who isn't happy to be found and resists the idea of coming back: "I'm done. I don't miss that world. I don't need it anymore. I still have money left, and I don't feel like shit anymore. I'm not injured. I'm done. I'm not going back." But after Bree leaves, Lefty puts on her shoes and starts shadowboxing. Comes back to the gym. Even consents to an interview, telling her story: Teen prostitute, raped by her pimp, gave up daughter for adoption, they're estranged now—and Bree tells Lefty she was her inspiration during her parents' abusive marriage ... and crosses the objective-reporter line into the bedroom.

Invigorated and inspired, Lefty heads back to the ring, facing the opponent who called her out in a well-edited, stylized minimalist scene that caps her comeback, leading to a rewarding ending.

Vespoli's challenging direction (from her own script) builds its story out of bits and pieces with clips, flashbacks, short cryptic scenes explained by subsequent bits of dialogue, all within the classic framework of the reporter trying to piece together a subject's life from talking with people who knew her—and in this case, the subject as well.
