Fort Santiago is an acropolis on the bank of the Pasig River, built in 1590, in the newly founded Manila city of the Philippines and was used as a prison in which many people were executed during the Spanish colonialisation and World War II. The film shows tourists visiting the site, as well as various views of its interior, bridges, buildings, fields, emergency exits, and many cells that determine its use. Also on the walls we see signs with historical information about the fortress. The film's final shots are from the building in which the Philippine national hero José Rizal was imprisoned until executed.
