There's a small coven of witches being threatened by a priest who's more than he seems. An upstart merc of a vampire and his pack of werewolves are aiding said priest for the right amount of money. The only one who can help the witches is a vampire who plays by her own set of rules and takes crap from no one.

And she has one method to solve most of her problems: shoot it, and if that doesn't work, well beat the wanker into submission.

Just one problem though, being one of the good guys means you have more than your own back to watch and can seriously throw you off your game.
