A visual and musical reflection of nature's rhythms, starting from time loop sequences of the sea taken during the course of a day in Finistère, Brittany, and marked by the rhythm of the tide. The beach fills with umbrellas, people, and animals as the tide flows out, leaving vegetal remains and man-made objects. Towards evening, the sea returns, completing nature's daily cycle, and night begins to fall to the steady rhythm of the surf beating the shore.
