When his devout daughter is possessed by the spirits of two revengeful children in order to exact revenge on their remorseless nurse, an accused and suspended priest must pull himself together and exorcise her before she kills the nurse- who happens to be his wife.

I'm honestly not getting much intrigue out of your explanation about why the children are angry.? I think the priest being "suspended" in some way is interesting.? And him trying to expunge the spirits from his daughter before they kill his wife is interesting.? I think this would make for a very clean logline too:

A disgraced priest must exorcise vengeful spirits from his daughter before she kills his wife.

Definitely see if others agree and disagree with me, however, before taking my advice.

Agreed with most of the above - the loglie is too wordy and the narrative it describes is slightly confusing.

What do you mean with "...an accused and suspended priest..." accused of what? Child molesting? Murder? Fraud? Has he just been accused or has he been convicted?

To a large extent, this would form the image of the character in the audience's mind as either a victim or aggressor. Therefore, you'd need to clarify this in the logline.

I like this concept and think I have seen either the movie that provoked it or one similar.? There are areas of easy trimming, and differing tangents to take, but one such take might be the following, which leaves the priest's battle less articulated since it appears only a tangent to the central theme. It *could* be far more involved but that would be a differing script.

If this were mine, I would tie the priest's wayward state to his inner struggle with the unacknowledged awareness of his wife's true nature, but.. that is complicated.

"A wayward priest's daughter is possessed by the spirits of two children who seek to kill their evil nurse, forcing him to seek redemption in time to exorcise his daughter, only to discover the evil nurse is also his wife."
