1993. Following a car accident that left him with amnesia, Ahmed returns to his home village, where nothing seems familiar, not his wife or children. His youngest, frightened by Ahmed's bandaged face, fears him deeply. Every night, strange visitors whisper litanies in an unknown language. Who are they? Why is Ahmed missing the index finger on his right hand? Why does his neighbor worry him? In the present day, an elderly Raqi is battling Alzheimer's. His disciple worries about him: Raqi's trembling right hand is missing its index finger. As possessed people continue to speak in mysterious languages and violence spreads, Ahmed fears regaining his memory, while his disciple fears that his master's decline may unleash an atavistic disease.
