Built in the 1970s on a European model at the edge of Abidjan, between the Yopougon district and the Banco rainforest, MACA was designed to hold 1,500 inmates and now holds up to 5,000. This film goes inside the largest prison in Côte d'Ivoire to document how a facility that overcrowded still functions day to day, through the guards who run it and the inmates who have built their own order within it. Different departments of the prison get their own portraits, showing how work details, hierarchies, and informal arrangements between prisoners and staff keep the place from collapsing into chaos. Rather than a story of pure brutality, the film traces what it calls a system of conflicting solidarities, where survival depends on alliances that cut across the line between captor and captive. Interviews with staff and prisoners carry the narrative, filmed inside the cell blocks and workshops, offering a rare look at an institution normally kept out of view of the Ivorian public.
