Storyline:In 1973, the professional tennis player Billie Jean King (Emma Stone) is the world's most elite at the provisional climax of her career. But the many tournament victories and fame are not all for her, because King, who feels much more than just friendship for her confidant Marilyn Barnett (Andrea Riseborough), also has a vehemence for the equality of women. Bobby Riggs (Steve Carell), on the other hand, has had his best years behind him and has also been struggling with his gameplay. The former champion would like to know it again and revive the fame of old days. He is even ready to risk his reputation. In the public, he represents the opposite opinion to that of King, and thus the inevitable collision in a Tennismatch of the sexes, which is to enter as a "Battle Of The Sexes" in the history.
