Cuatro paredes

María, a Madrid architect, discovers her new project — renovating an abandoned prison — eerily mirrors her own life. Every blueprint, every calculation becomes a metaphor for the cage she's built around herself. Client meetings transform into interrogations, negotiations into courtroom proceedings. Gradually, the line between professional duty and personal imprisonment blurs. The only person who understands is an ex-convict working on the construction site. Their conversations through concrete and rebar become the key to freedom sought not by the building, but by its creator.
