A historic journey in terms of an essay through the use of murals and political paintings in Teheran and a film for which its author has been sentenced to six years in prison and 223 lashes in his country. Keywan Karimi, through two male voices and a female voice, invites us on a journey around the walls of the Iranian capital, such as the only space where the freedom of ideas and expression can be developed. Also the propaganda of the regime. The revolution and its movements against it have fought to speak on walls on which aerosols do not cease to write "Down with the Dictatorship", in the complicity of the night.
