In the heart of a high-security prison, a group of inmates struggles to survive the brutal life behind bars, where relationships are forged and broken under the pressure of confinement. The protagonist, a young man with a troubled past, is sentenced to several years in prison. Upon arrival, he faces a hostile environment where violence and betrayal are part of everyday life.
As he adapts to prison life, the young man forms connections with other inmates, including a veteran who acts as a mentor, teaching him how to navigate the complexities of the penal system. However, the real challenge begins when rivalries between gangs within the prison arise, igniting a power struggle that endangers not only the lives of the prisoners but also the fragile friendships that have been formed.
With a backdrop of music and singing resonating through the walls, the protagonist discovers an unexpected escape: music. Along with his companions, he forms a musical group with the goal of sharing their story and redeeming their lives through art. However, prison is not a place where dreams come true easily, and every note can be a reminder of suffering and hopelessness. Will he find a spark of hope in the midst of darkness, or will he fall victim to the shadows that dwell behind those walls?
