About El Marginal
El Marginal is an Argentine prison drama created by Sebastian Ortega and produced by Underground Producciones. It premiered on the public broadcaster TV Publica in 2016 and later reached a wide international audience through Netflix. The series is set inside the fictional San Onofre penitentiary, a decaying maximum security prison where the line between guards and inmates is blurred and where survival depends on alliances, debts, and reputation.
The first season follows Miguel Palacios, a former police officer who enters San Onofre under the false identity of Pastor as part of a covert operation to locate a kidnapped young woman whose father is a judge. To complete his mission he must earn the trust of the prison's most powerful faction, led by the Borges brothers, while concealing his true purpose from inmates and corrupt officials alike. Later seasons function as prequels and continuations, expanding the backstories of the Borges family and the institution itself.
Praised for its gritty atmosphere, ensemble performances, and tense pacing, El Marginal became one of Argentina's most internationally recognized scripted series and helped popularize Argentine prison drama abroad. Across five seasons the show built a layered portrait of life behind bars, examining loyalty, corruption, and the cost of power within a closed and dangerous world.
