Dublado e Legendado no OverFlix. The Great Dismal Swamp: an uninhabitable wasteland, covering parts of Virginia and North Carolina. A treacherous den of poisonous water snakes, blood-sucking insects, spiders and predators like black bears and lynxes. But some had no other option except braving these dangers, like fugitive slaves, who needed a way to escape the cruelty of their white masters.
