Set fifteen years after the initial movie, The Exorcist III centers across the philosophical Lieutenant William F. Kinderman who is exploring a baffling string of murders around Georgetown that all contain the hallmarks of this Gemini, a deceased serial killer. It eventually leads him to a patient at a clinic who has recently begun to speak, detailing the murders and promising he could be the The Gemini, but bears a striking resemblance to Father Damien Karras.
