Set in a provincial Russian town, Demons (also known as The Possessed or The Devils) portrays the destructive rise of radical political groups. The story follows a circle of nihilists whose ideological games escalate into manipulation, violence, and chaos. Through complex characters like Stavrogin and Verkhovensky, Dostoevsky exposes the dangers of extremism, moral emptiness, and the collapse of spiritual values. It is both a political thriller and a deep psychological study of how ideas can become destructive forces.
