Following disastrous floods, a vast construction project is in the process of revitalizing the Rhone by removing the concrete straitjacket, and instead enlarging the river's bed to promote river life. The filmmaker follows the development of this unusually inclusive project through its diverse protagonists, including hydrobiologists, fishermen, farmers, engineers and concerned citizens. Their divergent concerns permit a fuller and unbiased understanding of the complexity of such a project. As a result, this engaging and lyrical film is a journey that prompts a universal questioning of our past and future relationship with nature and territory.
