A young and eminent Professor of the University of Bologna finds himself at the centre of a difficult investigation.
He turns his back to everything and ends up on the peaceful banks of the River Po where he finds the ruins of an old building and takes possession of it.
A series of histories of friendship, everyday life and love between the professor and the inhabitants of the place develop around the professor’s new dwelling place in a sort of spontaneous meeting of minds with the instant where all possible realities can be experienced.
