A young rookie cop responds to noise complaint that turns sour when the offender turns out to be a mentally disturbed drug addict that forces him to take a drug that allows him to see demons.

I think this sounds really interesting. I love stories like this where you have a normal guy that gets thrown into a situation. I was going to give critique, but patrockable said everything I had to say. This sounds really cool though.

Sorry, I meant "demon revealing"

You're welcome, glad I could help!

The "stop being able to see demons" goal sounds to me like a "refusual of the call" reaction, I'd say the main action would be to fight the demons and save the world, so this would be better for your logline.

Also, maybe "demon world revealing" drug might better suggest that the demons were always there?

So something like:

When a deranged addict forces a rookie cop to take a "demon revealing" drug, he must destroy the demons to save the world. :)
