Tumberos tells the story of a famous upper-class lawyer, Ulises Parodi, unjustly imprisoned for the alleged murder of dancer Gisella Acosta, who with the passing of the chapters will adapt to the tumbero world of the Parque Patricios prison, becoming a rival to the leader of the prison wing, Guillermo Willy Marmotta. In turn, outside the jail, the lawyer Lorena Rodríguez must search for the real murderer and thus be able to prove Parodi's innocence.
