Off the coast of Sicily, at the Aeolian Panarea, a group of well-off friends including Claudia, her unhappy best friend, Anna, and the latter's fiancé, Sandro, set off on a yachting cruise. And then, unexpectedly, when the party casts anchor at the isolated volcanic island of Lisca Bianca, young Anna will vanish into thin air. To no avail, as the remaining friends along with the police comb the inhospitable lava island, little by little, an uncomfortable clandestine connection will form between Sandro and Claudia, following Anna's puzzling disappearance. Who knows where Anna could be? Did she escape a loveless marriage or did something bad happen to her? Furthermore, is Sandro and Claudia's adventure heading somewhere?—Nick Riganas
