A mixture of archive images and fictional scenes, the film is a tribute to the city of Algiers, which is at the origin of the project. Random walks and meetings, Simon and his wife, a couple of French tourists, discover Algiers. Simon recognizes an Algerian in a bistro whom he was once tortured. The man stares at him. Panicked, Simon flees. "Tahia Ya Didou is the only film by actor Mohamed Zinet. Born from an order from the city of Algiers, which expected it to be a tourist documentary, it was not to the taste of the authorities and there is no not cut, no theatrical release.Despite everything, it has become a cult film, Tahia Ya Didou is much more than a promotional documentary.A tribute to the city of Algiers, to its inhabitants, it has an unclassifiable tone, cohabitation of comic burlesque and tragic reminiscences of the country's painful past."
