"Hardball: The Girls of Summer" follows the top female baseball players in the USA, all members of the globally ranked US Women's National Baseball Team. They play BASEBALL - not softball - and fight for equality, recognition, and acceptance in a sport that continues to exclude women and girls. These trailblazers chase their dreams of winning a Gold Medal at the Women's Baseball World Cup, playing professional ball, and creating opportunities for the girls coming up behind them. This is their quest to prove that women and girls belong on the baseball diamond and have a place in America's Pastime. "Hardball" invites us into the exciting, passionate, and truly American story of baseball-loving underdogs taking on the world as they struggle to play a game against all odds. It confronts our cultural relationships to gender roles, women's athleticism, and the expectations we, and others, have for our daughters. It introduces much-needed role models: athletes who are leveling the playing field by playing the game they love no matter what. Ultimately, "Hardball" is a story about having the freedom to pursue dreams, hopes, and one's own path, regardless of gender. Sixty years ago, a color barrier fell in the wake of Jackie Robinson's trailblazing career. Now, in the heart of the #MeToo Movement, more barriers are being challenged and, ultimately, falling. "Hardball" dives deep into world of women's baseball to follow 5 of the sport's most elite American players. These girls of summer fight for equality, simply by playing the game they love and refusing to take "no" for an answer.
