The film dwells on the decline of Claudia (43), an aristocratic woman, during 1977, amidst the coup d’état in Argentina.
For years, Claudia has endured a violent relationship with her husband Carlos (55), a powerful businessman linked to the navy and to American entrepreneurs.
Their marriage falls apart, daily life becomes untenable and their sexual life turns frustrating, partly due to Carlos’ impotence.
Desperately trying to to get out of her bourgeois bubble and trapped in her desire for motherhood, Claudia will start a sexual and affectionate relationship with Gervasio (50), a horse-keeper, who has recently joined the equestrian club she frequents.
Hector (40), ship lieutenant, Carlos’ friend and business partner in some of his enterprises, becomes obsessed with Claudia. Upon Hector’s spying on Claudia, he discovers her affair with Gervasio and bribes her by sexually harassing her.
Terrified to lose his wife, Carlos will try to please Claudia by promising to help her become a mother, no matter what. With the help of Hector and without Claudia’s knowledge, Carlos decides to seize a baby who is about to be born in ESMA (army building, which served as a clandestine centre for detention, torture and extermination during the coup d’état).
Claudia unintentionally unfolds her husband’s arrangement, realizes the danger involved and tries to take refuge in Gervasio, who is not simply a horse-keeper, but an undercover member of the E.R.P. (Argentine guerrilla organization, of Trotskyist origin, who fought against the coup d’état). Gervasio is performing espionage on the military men who attend the equestrian club.
Mistakenly suspecting that Claudia is tricking him with Hector, Carlos sets a trap for them.
Now, Claudia must overcome the unravelling of a threatening future.
