I sjette episode fortæller vi om tennislegenden, Billie Jean King. Hun vandt utallige trofæer, imens hun kæmpede for ligeløn i tennis, stiftede WTA-touren og vandt den ikoniske "Battle of the Sexes"-tenniskamp over Bobby Riggs. Hun satte gentagne gange sin karriere på spil for at revolutionere den sport, som hun elskede.
