Not the characters or the common spaces given and taken from time: the real protagonist of the film is the river. The scenes, taken along the shores of the Sarno river, from its source to its mouth, to the neighbouring beaches, draw up the transition, in just 24km, from the fruition of the river to the impotence at it - maybe reflecting that “you cannot step twice into the same stream”. the word, taken from Literature and here used as title , surrenders the images to a reading order in which the beginning and the end are hard to identify - to the utopian gentleness.
