White Horses follows Emily Grimes on a transformative journey along Scotland's north coast with two horses and a surfboard. Balancing her fast-paced life running a surf school with her passion for solo adventures, Emily confronts her self-worth, expectations, and fear of missing out. Removing familiar comforts, she explores the raw essence of both sports. The film captures the contrast between slow, intimate horse riding and energetic, rhythmic surfing, with an original score by Diva Jeffery of Jadu Heart.

Amidst this adventure, Emily discovers an abandoned cottage, frozen in time, revealing a stark juxtaposition of 1950s women's roles against the spirit of pioneers like Nan Shepard.

As the terrain shifts dramatically, evolving from the isolated Highlands to the suburbs of Thurso, so does Emily’s outlook. This voyage serves as a form of active rest for Emily, giving delayed gratification from her usual sources of adrenaline and dopamine rushes. This prompts a deep introspection into the interplay between surfing and her sense of self, and the immense pressure she puts on herself to achieve a "good" surf.
