"Oregano" is the story of a dysfunctional and very poor family, made up of four members: the mother, a former singer who failed in her career and expresses her frustration through anger and violence; the father, a former butcher who had to close his business after the 2001 crisis and was confined to a wheelchair; the youngest son, who does not finish elucidating his sexuality, escapes from reality building a universe of fantasies, but at the same time seeks to become independent; and the eldest daughter, who questions her identity and that of her family, realizing that she is the same age as her father. The family lives in a small house where individual conflict and frustrations are combined with group ones, which unleashes a chain of events that leads to the rupture of their traditional scheme.
