Set in a small, traditional Sicilian village, Maria (Angela Molina) is married to Sergio (Massimo Ghini), a fisherman who is frequently away at sea for extended periods. Loneliness and emotional neglect weigh heavily on Maria, who finds herself drawn into a passionate, secret affair with a local man, Giuseppe. When her husband returns, the illicit dynamic creates intense jealousy and moral conflict within the conservative, honor-bound island community, leading to a tragic breakdown of trust and revenge.
