At a psychiatric institute in Northern California a number of patients appear to have been cured by a brilliant young psychiatrist, and the process has endowed them with phenomenal mental powers. FBI agent Mark Delaney comes to believe that the patients have not actually been cured-instead he thinks that their minds have been taken over by entities of some kind.
He and his team set out to uncover the truth behind this seemingly miraculous healing process. They discover that one of the patients has been transformed into a ruthless, power-hungry killer, a man whose knowledge can endanger the future of the human race; a man who will do whatever it takes to ascend to the pinnacle of power-the presidency of the United States.
This megalomaniac is determined to crush anyone who stands between him and the highest office in the land. Delaney is equally determined to bring him down, knowing that the fate of his country, and perhaps the entire future, hangs in the balance.
