Model Prison. Barcelona 1977. Manuel, a young accountant, imprisoned and awaiting trial for committing embezzlement, faces a possible sentence of between 6 and 8 years, a disproportionate punishment for the crime committed. Soon, together with his cellmate, Pino, he joins COPEL, a prisoners' collective that will fight for the rights of common prisoners and amnesty. A war for freedom begins that will shake the Spanish prison system. If things are changing outside, they will have to change inside too. A story of friendship, solidarity and freedom, inspired by real events.
