Enoch, a righteous man chosen by God, receives a vision of the future. He is told that God will come to Earth in power and glory, striking fear into beings called Watchers. The Earth will be destroyed in judgement, but the righteous will be protected and prosper. Enoch is then shown that the Watchers, led by Semjaza, lusted after human women and taught mankind harmful arts. Their offspring were giants who consumed humanity's resources. The Watchers are condemned by God and their leader Azazel is bound. The archangels are sent to destroy the Watchers' children and imprison the Watchers until Judgement Day. Enoch is then hidden by God and writes down his visions.
