Speaking to a therapist, he discusses his poor relationship with his late brother Isaac (Jesse Williams). Although Jacob believed his brother died during the war, he is shocked to find Isaac has returned. However, Isaac doesn't appear to be in good health and although Jacob tries to help him, Isaac accuses him of trying to kill him. Meanwhile, Isaac's return leads to Jacob having horrifying hallucinations of demons coming after him. Jacob's life continues to spiral downward as he suspects everyone around him of a conspiracy.
