Committee Opposing Devils (C.O.D.) members hunt down and exorcise demons passing as humans whenever they can. When a woman who senses the presence of devils reports something big and important has changed they interpret a signal seen in the sky worldwide as a warning to the devils everywhere. The devils (who indeed are passing among us) fight back as the C.O.D. call for mass volunteer exorcism rituals worldwide. They use what they know of humans to twist, slow down, and frustrate those planned events. Finally a major human C.O.D. egotist and a top demon have it out in a personal rivalry that creates more questions than it answers.
