Spurred by the desire to understand the effect of climate change and human intervention on the future of the Po River, a reporter and a filmmaker go for a bike tour down the river. Along the way, they discover that water levels increasingly mark highs and lows, maintenance works were poorly planned, the agencies overseeing the river seldom cooperate with one another, the national government is disinterested in what is happening. The local residents try to make a living in an area that has been largely neglected despite the many resources that could be used to protect it.
