It’s been fifteen years since Lt. William “Bill” Kinderman’s (George C. Scott) good friend Father Damien Karras (Jason Miller) was killed performing a rite of exorcism on a young girl in this Georgetown neighborhood. Fifteen years, also, since serial killer James Venamun (Brad Dourif), dubbed the Gemini Killer, had been executed, ironically, on the same night as Father Karras’s death. So why now, all these years later, was Kinderman being called in to investigate a string of homicides which looked for all the world like the work of The Gemini himself? The crime scenes bear all the hallmarks of the Gemini’s original killings, including those police had kept from the public making a copycat killer unlikely. This time around, though, there are a few twists. A different set of fingerprints is found at each of the scenes and the only people spotted are elderly people, very unlikely suspects. Kinderman is disturbed and frustrated both by the events themselves and by his personal reactions to them when the head of the local hospital’s psychiatric ward, Dr. Temple (Scott Wilson), asks him to come and look at a patient who has recently begun claiming that he is the Gemini Killer.
