Paradise Falls is a slave trading center under the scorching sun of a scorching nuclear desert. Slave cages are everywhere. Carriages loaded with miserable, tortured slaves are parked in a special parking lot, and the slaves the traders ride are tied to posts like ordinary, tortured horses. Buyers of all ages are also everywhere – bargaining, arguing, buying, laughing, drinking, and so on. The world has become cruel after the nuclear war, and therefore compassion for slaves is a rare thing.
