Take that, Ronda Rousey. The former mixed martial arts champion — now a budding movie star with turns in “Entourage,” “The Expendables 3” and “Furious 7” — is challenged by her former Ultimate Fighting Championship peers in Rob Hawk’s “Fight Valley.” Don’t get me wrong; she’s not in the movie. But a few of her erstwhile rivals take a swing at the big screen (and Ms. Rousey’s Hollywood status) in this punch-drunk action drama, starring Miesha Tate (the former U.F.C. women’s bantamweight champion); the featherweight Cris Cyborg (Cristiane Venancio, but here billed under her nom de octagon); and Holly Holm, who bested Ms. Rousey in a championship bout in 2015.

There are non-U.F.C. actresses, too, including Chelsea Durkalec and Erin O’Brien, playing Tory and Duke, lovers who are part of a Camden, N.J., street-fighting crew, the Knock-Around Girls. Among their tormentors is a female gang led by the intimidating, um, Ms. Cyborg. When Tory, striving to raise money to leave Camden, accepts a challenge at the notorious underground ring the Yards, she dies, and her distant, delicate sister, Windsor (Susie Celek), investigates. Windsor joins the Knock-Around Girls, who include Jamie (a mischievous Cabrina Collesides) and Yanni (Kari J. Kramer), and learns the “No. 1 rule of the Knock-Around Girls: Make sure the other one is safe.”

Cue the inevitable training montages, as Windsor acquires callused knuckles under the tutelage of Jabs (Ms. Tate, the picture’s true star), the owner of a gym. Disappointing plot twists ensue in a climactic brawl starved for snappier choreography and editing. Ms. Tate, who has a sequel brewing, is clearly the winner.
