Not sure if this story is running yet...
In case it's not, here's a non-trivial idea, probably easy to set up, and difficult to predict.
We have over here a parish priest, Father McLaren, who in point of fact is as honest, upright and God-fearing as it is possible to be. However, the parish is in a fallen city (location left to the imagination) where some of the priesthood have abused young children.
Over there we have the older sister of Timmy Silinger, who's been introverted and emotionally retarded. In counseling he accuses Father McLaren of abusing him. It's true he was abused, but he is terrified of the true abuser, who said he would kill the boy if he ever revealed the abuser's identity. So Timmy accuses Father McLaren.
Sister stalks priest.
Does she find out the truth somehow? Do former enemies meet and track down the real child abuser? Does Timmy finally come clean and tell the truth? Or does Father McLaren end up unjustly imprisoned? Does he fall in love with the sister and leave the priesthood? Or just make passionate love to her one time? I don't know any of the answers.
