Biagio Martini is a successful lawyer. But he fears thunderstorms, and the memory of what happened in the old house by the river, when he was a child, corrodes his soul. Agata Rubino, on the other hand, is a fearless and courageous woman. She fears nothing as she hunts down the one who destroyed her life. Biagio and Agata do not know each other, they have never met; they do not know that their destinies are about to intertwine in an inexorable way.
