Metal band S7N embarks on a tour unlike any other—five concerts inside Mexico City’s prisons, inspired by their former drummer Fabián, who found healing behind bars through music. Sin Barreras is raw, loud, and powerfully emotional. This isn’t just about music; it’s about connection, redemption, and how shared sound can forge humanity in even the harshest places. Through riffs, rhythm, and radical empathy, the film reminds us that freedom isn’t just physical, it’s spiritual.
