La Model Prison. Barcelona, 1977. Manuel, a young accountant, imprisoned and awaiting trial for embezzlement, faces a possible sentence of between 6 and 8 years, a disproportionate punishment for the crime he has committed. Along with his cellmate Pino, he soon joins COPEL, a group of prisoners that will fight for the rights of common prisoners and for amnesty in Spain. A war for freedom thus 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.
