A dangerous serial killer charms his way into a single Mom’s life which brings a talented FBI agent out of retirement to work on the case whilst supernatural Neptune is also awakened to help.

Unclear what’s actually happening here…on what case is the retired agent working? The serial killer case? What brings him out of retirement? It can’t be the death of this single mom, because apparently she’s only being charmed by the killer, not killed…and describing such a person as dangerous is like calling the sky blue; it’s pretty much understood. He needs a better adjective to make him unique and compelling.

But then…what does “supernatural Neptune” have to do with anything? Are we meant to imagine Poseidon, god of the sea? What’s his involvement? Is the Little Mermaid in trouble? This seems like a totally different movie, and a completely separate concept from the first half of the logline. If there’s a supernatural element, it shouldn’t be mentioned at the end like that, almost as an afterthought; it should be clear and up front. Nothing wrong with an otherwise reality-based plot containing supernatural elements, but they have to feel like part of the story, not another story entirely.

In one sense this is a rather concise delivery of characters and story elements, which is good for a logline — but the ideas presented don’t add up in combination.
