On the island of Ginestra, a small green rock in the center of a lake, the Reffi family's villa is the safe haven for old Antonio, an ENT doctor with a sharp irony, and his two sons. Carla, the eldest, dedicates herself to writing amidst her parent's barbs. Celestino, the younger brother, became a doctor to answer his father's prayers but prefers to turn his intuition to mathematics. With the penniless cousins Vittorio and Jole and the two maids, the inhabitants of Ginestrin are complete. Life on the island flows peacefully until two hotel thieves fleeing from the police land on its shores: Guido, a gambler with a passion for painting and Beatrice, beautiful, cheeky and fatal. The arrival of the two fugitives and their revelations shatter the perfect world of the Reffis,
who find themselves against each other faced with a moral doubt: should they denounce the two guests or give them a chance at redemption? It is the beginning of a vortex of tension that upsets the quiet of the island and the souls of its inhabitants, who between impossible loves, escapes, lies and envy will have to come to terms with their truest nature.
