Artist and conservationist Zoe Lucas lives mostly alone on a remote island in the Atlantic. For decades she has been observing the changes in the landscape, the population of feral horses, seals and seabirds. She creates art from masses of washed-up plastic waste. Director Jacquelyn Mills also experiments with what she finds, investigating the materiality of film. GEOGRAPHIES OF SOLITUDE is not only a poetic portrait shot on 16mm, but also the starting point of a gradual collaboration between two women that blurs the boundaries between art and science.
