Hi, I'm trying to find out the name of a film that I remember seeing YEARS ago.

I know it was American and that at the end there was a burning barn or building. I think there was a glowing jar and people dressed in white. I think there was a cult or covenant.

If anyone can help (I know the description is vague) that'd be great.

Do you remember some of the story? Maybe names of characters or actors?

Try the Devil's Rain

It might be this, although I don't remember the melting. I seem to remember lots of girls in long white robes. I was quite young when I saw this, so am not clear.
