Professional climber Emily Harrington has summited Everest, 8000-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, a near-fatal fall forces Emily to reckon with what she’s willing to risk. Equal parts gripping survival story and intimate portrait, Girl Climber isn’t just about breaking records, it’s about breaking barriers. Amongst Yosemite’s legendary boy’s club, Emily isn’t just proving she is the best *Girl Climber -- she's proving she is one of the best. Period.

In April of 2025 Hamish McArthur made the second ascent of Megatron (V17/9a) in Eldorado Canyon, Colorado. With hints to his artistic practice, this visual collaboration allows Hamish to take the viewer into an incredibly personal space exploring his mental process and his ideas around awareness. To let go of unnecessary narratives about ourselves and our world. To become aware that we are everything and we are nothing, and in that awareness we can become invisible, we can let go of the self and find what lies beyond.
