Jeannie Epper and Zoe Bell are two women who get hurt for a living -- they're Hollywood stuntwomen, who take the falls and dodge the punches while taking the place of glamorous stars. Epper's big break came when she was hired to stand in for Lynda Carter on the Wonder Woman television series in the 1970s, while Bell made a name for herself doing Lucy Lawless' stunt work for Xena: Warrior Princess. Double Dare is a documentary which looks at the lives and careers of these two women, as well as their friendship. Epper, in her early sixties, finds herself dealing with ageism in the entertainment industry, just as she's dealt with sexism much of her life, as she struggles to stay in the game, while Bell learns from her older friend not only the nuts and bolts of stunt work but the trails Epper and her compatriots had to blaze to be respected in their profession. Double Dare also features appearances by Quentin Tarantino and Steven Spielberg. ~ Mark Deming, All Movie Guide
The film begins with Bell finishing her work on Xena and Epper searching for continuing work in Hollywood despite her age, even considering liposuction before forgoing cosmetic surgery. Xena ends its run and Bell struggles with what to do next in her career. Meanwhile, Epper negotiates to have a women's category included in the Taurus World Stunt Awards (also called the World Stunt Awards). Bell is invited to the United States for a Xenaconvention. There she meets Epper and, obtaining a ticket with the help of the documentary crew, attends the stunt awards. Though initially receiving an offer to work on a series starring Victoria Pratt, Bell ultimately does not get the job and returns home to New Zealand.
The film resumes one year later with Bell still training, though unemployed, and planning a move to America. She stays with Epper, who is attempting to get a job working on 2 Fast 2 Furious with Terry Leonard. Epper helps Bell assemble the necessary elements for her to start her career in America, such as a CV and head shots. She also warns Bell about the deceptive nature of Hollywood, instructing her to list her weight as 130 lbs when Bell actually judges herself to be 145. Epper takes her to a training session, where they encounter Quentin Tarantino's stunt scout Kenny Lesco, who is looking for someone to doubleUma Thurman in Kill Bill. Lesco arranges for an audition on the same day as the training session. Epper and Bell drive to Tarantino's Culver City training center for the audition, there meeting Tarantino himself as he evaluates Bell. Much to her delight, she earns the job doubling Thurman and is sent to train in Beijing with Yuen Wo Ping.
Eventually Bell begins filming for Kill Bill, Part 1; the documentary shows her working on the fight between Beatrix Kiddo (Thurman) and O-Ren Ishii (Lucy Liu) and her bodyguards, as well as several other fight scenes. The film ends with Epper being honored by the Stuntmen's Association and Bell speaking optimistically about her future as an adult.
