Ahead of next month's Women's Rugby World Cup, Guinness Europe has debuted an inspiring and uplifiting film that pays tribute to a group of women's rugby players who pioneered the sport in Japan in the 1980s.

In the film we meet former players from Liberty Fields RFC, a Tokyo Club, who represented their country at the 1989 women's World Cup. With footage from their playing days interspersed with interviews from the present day, we learn about their love for the sport, dedication to practice and how even a crushing defeat on the world stage made them glad that there were so many other women playing top-level rugby in the world. 

Along with the five-minute documentary seen here, there's a TV ad version running in the U.K. from tonight. The campaign is by AMV BBDO and the film was directed by Eliot Rausch at Stink Films.
