His wife is murdered before his eyes and his twin sons are taken away to another plantation. After a harrowing escape, Tobias searches nearby slave camps for a high priest of his native African religion. Seeking vengeance, they evoke the spirits of their elders and unleash a malevolent force upon his master. Two hundred years later, the horror has reawakened, targeting an innocent man, paramedic Galen Morris. Suddenly, a seemingly unstoppable executioner stalks his every move. Forced to run, Galen must unravel clues while staying one step ahead of his otherworldly enemy. Dark Justice tells the stories of two men, both running for their lives. While one man's run brings an unspeakable terror into the world, the other man's run is a dangerous quest to stop it.
