La Ciénaga
Mecha (Graciela Borges) and her family are nearing the end of their summer holiday when her cousin Tali and her family are forced to come and live with them. No one ever seems to go anywhere; parents and kids lay in bed, half-naked in communal sloth, but there are powerful undercurrents running beneath the seemingly languid country-house atmosphere.
