A writer, S., visits a life-sentenced young man in prison with special permission. Martín Santos has gruesomely killed his father. The writer intends to write a play based on the meetings with the young inmate, focusing on Martín's relationship with his father and the story of his patricide, in which the inmate himself will star.

However, the authorities, while initially consenting, later prohibit Martín from participating in the performance by playing himself and only allow him to watch a general rehearsal of the play without audience participation. Thus, the writer must find a substitute actor to play the role of Martín in the theater.

The play depicts the meetings between the writer and Martín on one hand, and the writer and the actor on the other, during the time the play is being written, as the relationship between S. and both gradually evolves. Is Martín a modern Oedipus? He killed his father knowing that he was his father; his life did not experience the tragic downfall from greatness to ruin, no fate, no god marked his fortune unbeknownst to him.

However, he lives a tragic personal story in which he wants to end his tormenting father. The only common element with Oedipus is the patricide, but there are also differences in this context. Can he be characterized as a tragic hero? The play, which belongs to the genre of autofiction or self-fiction, a type of writing in which Blanco has excelled in recent years, has traveled around the world.

The inaugural performance of the National Theatre of Uruguay, directed by Blanco himself, has been invited to major festivals and significant contemporary stages worldwide, translated into more than ten languages, and staged in many countries with enthusiastic reception from critics and audiences.
