Environmentalist Zoe Lucas has cataloged flora and fauna on Sable Island, a thin strip of land off the Canadian coast, for decades. The island’s only full-time human inhabitant, Zoe embarks on solitary excursions to observe the sand dunes, starry skies, wild horses, and washed-up plastic waste.

Blending abstraction, landscape, and portraiture while also using environmentally-friendly methods, Jacquelyn Mills’s acclaimed film barnacles itself to an island and its inhabitants. Teeming with invention and generosity toward the world, this beautiful documentary is a real treasure of ecocinema.
