1974 film by Pancho Guerrero

They are both alone. They need each other but, at the same time, they despise each other. Siblings Marcos and Susana are unable to heal the old wounds festering within them after the death of their mother. When Susana sells their mother's flat, she deprives her brother of the home where he had cared for their mother his whole life. Marcos's need to start living again surfaces when his sister forces him to leave Buenos Aires for Uruguay.

Mama Cora, who is almost eighty years old, has three sons and a daughter. She lives with one of them, who has serious financial problems. The family meets one day to celebrate an anniversary meal, and that is when the problem arises: which of them will take care of her?
