The global rise of demonic possessions brings together five exorcists from different faiths to combat an evil unlike any they have ever encountered.

Good point. Maybe a good case for “five exorcists form an unlikely fellowship.”

I agree with Richiev, Further, as you mention 'different Faiths' I'm expecting a preview of some payoff, do they have to compromise to work together? Does the combination of faith make them stronger? "Five faiths are better than one!"

Five exorcists from different faiths unite to combat a global increase in demonic possession.

(In your logline you also say, to combat an evil unlike any they have ever encountered... but that sentence is vague, so I dropped it.)

Is this a movie or TV show?
