Set in Sinera, a deeply conservative and claustrophobic fishing village on the Catalan coast during the early 20th century, Laia is a fierce, independent woman trapped in a miserable marriage to Quel, a coarse and volatile fisherman. Seeking an escape from her grim domestic reality, Laia enters into a passionate, turbulent extramarital affair with Esteve, a wealthy local landholder. The affair shatters the delicate social balance of the highly religious community, triggering a chain reaction of intense jealousy, local gossip, and systemic misogyny. As Laia struggles to assert her freedom, her defiance of traditional marital expectations leads to a tragic, violent clash between her husband, her lover, and the unforgiving village collective.
