Professional climber Emily Harrington has summited Everest, completed numerous first female ascents of 5.14 routes, scaled 8,000-meter peaks and dominated the competition circuit. But her greatest challenge extends beyond the physical. To cement her legacy in the male-dominated world of elite rock climbing, she sets her sights on a career-defining 24-hour ascent of Yosemite’s El Capitan. Caught between the pursuit of personal ambition and the ticking biological clock of life, Harrington grapples with what she’s truly willing to risk. Equal parts gripping survival story and intimate portrait of a woman who deals with self doubt, Girl Climber isn’t just about breaking records. It’s about breaking barriers. Among Yosemite’s legendary boy’s club, Harrington doesn’t prove she is the best female climber ever — she proves she is one of the best climbers of all time.
