The film is about a pilgrimage that took place by the River Thames. As part of this journey, Célia Hay and Anne Vimeux walked from the Thames’ source to its mouth. They captured thus the isolation of living in autarky, the gestures of their everyday routine as well as some rituals. A certain sens of loss emerges from this strange pilgrimage. As and when the walk progress, some odd silhouettes and events occur. The physical and mental effort of the walk leads to a dissolution of the bodies which appear then as some kind of ghosts. Eventually, as their journey ends by the sea, they reach a certain state of sweet madness.
