Martina Navratilova and Chris Evert come from completely different places and play tennis in completely different ways. Chrissie is the all-American girl: practiced, poised, with perfect technique. Martina hails from Czechoslovakia, a Communist country, and her game is ruled by emotion. Everything about them is different, except one thing: they both want to be the best. But as their intense rivalry grows, something else begins to swing into place, and a friendship forms that will outlast all their tennis victories.
