"In the summer of 1944, when she and her friends were taking a walk on
the beach of Amagansett, New York, Anas Nin encountered a strange
scene. A woman was lying on the shore, letting herself be pummeled by
the waves while two people filmed it. Later, Nin found out the woman
was Maya Deren, an avant-garde filmmaker, who was filming the opening
scene of At Land (1945)."
