Desperate to jump-start her career, struggling actress Ruth heads to a casting call at an LA gym -- and quickly realizes it's not a typical audition.
Ruth Wilder, an actress struggling to find work, receives an invitation for an audition from her casting director. She arrives at an old boxing gym, where she and dozens of other women are auditioning for Gorgeous Ladies of Wrestling (GLOW). On the first day of tryouts, Ruth is dismissed by director Sam Sylvia when her acting skills come into conflict with the training; her day worsens when her purse is snatched by a group of skateboarders. With nowhere else to go, she begins watching professional wrestling videos to develop her persona and returns to the gym for another shot at the audition.
Things go awry when her best friend Debbie Eagan confronts her after discovering that she has been having an affair with her husband Mark. Their legitimate catfight in the ring inspires Sam to keep Ruth in the program.
