La Nona (Pepe Soriano) is 100 years old and lives in the midst of her poor Argentine family, eating them out of house and home. The desperate family members try every means they can think of to appease her appetite, including sending even the most poorly skilled out to work. In this black comedy, when they deposit her at the door of an old-age home, like some unwanted child, she is returned to them. They try to get her married off and in desperation eventually try to poison her. Nothing helps, and she outlives everyone, happily eating whatever she can lay her hands on.
