When American No 1 tennis champion Stella Myers loses out on her chance to be the first player since Steffi Graf to win a calendar grand slam, it makes her more determined than ever to try again the following year.
British No 1 Rose Winterburn has her heart set on being the first female British player to win Wimbledon since Virginia Wade in 1977 and doesn't want the grand slam grand plan of Stella Myers to get in the way of her dream.
As Stella and Rose battle it out at the four grand slams over the year in Melbourne, Paris, Wimbledon and New York, it's not just the pressure of trying to win these prestigious events that begins to take its toll on them.
