Mecha en haar man Gregorio brengen met hun vier kinderen de hete zomer door op een landgoed in een verraderlijk moerasgebied (La Ciénaga), in het noordwesten van Argentinie. Het huis heeft betere tijden gekend. Het zwembad is vervuild, scherven van gebroken wijnglazen liggen overal. Mecha is verveeld en drinkt teveel wijn terwijl haar man op de versiertoer gaat. Wanneer Mecha zich in een dronken bui verwondt, besluit haar nicht Tali met haar vier luidruchtige kinderen op bezoek te komen. Een bezoek waar niemand op zit te wachten. De sfeer is broeierig en onheil hangt in de lucht. Een opeenstapeling van gebeurtenissen brengt de families uiteindelijk dichter bij elkaar.
Nee, helaas is La Ciénaga nog niet beschikbaar op Netflix in Nederland.
