A violent epic leaping from the cosmological to the infinitesimal, Satan Repentant is a modern-day drama of revenge, resentment, and remorse, telling a new myth of what would happen if Satan tried to apologise and atone for all his crimes. Through that story, it explores ideas of power, of authority to judge right and wrong, and the dignity and shame that can be attached to admitting fault or insisting on self-righteous innocence. To prove his remorse, Satan is compelled to endure a test: become human, and live an entire life without succumbing to evil. The challenges this conceit imposes for human morality, theology, the notions of free will and good versus evil, precipitate a frantic and often violent battle over an individual's right to their own identity.
