Season 3 of Prison Break features a fictional Sona Federal Penitentiary, a prison, the most brutal of all depicted in the show till now. The location serves as the primary setting for the season's events, and according to reports, its portrayal draws inspiration from some real-life penitentiaries from São Paulo, Brazil. The inmates are brutal, but the prison is even worse. Amid this, Prison Break brings out some of the most compelling scenes of all time.
The real inspiration is Carandiru Penitentiary, which was operational from 1956 to 2002. This was once the largest prison in Brazil, housing 8000 inmates at maximum. In 1992, a prison riot occurred, which led to some tragic massacres. Read on to know the twisted truth behind the most notorious jail.
Here is what we know about the twisted truth of the real notorious jail that Prison Break took inspiration from
In the 1992 riot, 111 inmates were killed by military police. The event was further regarded as a human rights violation and has been featured in various documentaries and books. In Prison Break, Sona is depicted just like that— a prison with overcrowded cells, a lack of control, and rampant violence. In the series, Sona is portrayed as a prison without guards, where inmates govern themselves through brutal means, and escape is nearly impossible.
Moving to Sona in season 3 was a redefining and shocking twist. Fox River was a traditional U.S. prison with structure, guards, and routines—even if it was harsh. Sona, on the other hand, is an anarchic nightmare with no guards inside the prison walls. Inmates were police themselves, and it was all a game of the survival of the fittest, with the strong ruling over the weak.
Brad Bellick is shown to be the sadistic Fox River guard who wielded unchecked power in Season 1, now has become a powerless, abused inmate in Sona—stripped, degraded, and humiliated. Season 3 is more raw and gritty with tense storylines and limited episodes —only 13 as compared to the usual 22.
The season further featured blurred moral lines with Alex Mahone, once Michael's enemy, now his fellow inmate, becoming his ally. Hygiene is scarce in Sona, and violence is at its peak, with every man just trying to keep themselves safe till they can.
What happened in 2001 in the prison Sona is inspired by in Prison Break?

Following the tragic riot in 2001, over 100 inmates escaped from Carandiru, Brazil’s most notorious penitentiary. The escape involved a secret tunnel, dug over time beneath the prison. It was one of the largest prison breaks in Brazilian history.
In season 3, in the fictional prison Sona in Prison Break, we see Michael and three others— Whistler, Mahone, and Tracy McGrady- escape through a tunnel Michael engineers beneath the prison.
However, Prison Break shows a few inmates breaking out, but it mirrors the same real story and themes like covert planning, corruption, and survival.
Prison Break comments on some gritty social issues, the quality of life of inmates, and how quickly the system can collapse under pressure.
