They call themselves angels, but they're really mind-controlling aliens. 

Manipulating humans in their war to destroy one another. But they aren't the only monsters that go bump in the night. Hard up for cash, Howard King joins a shadowy organization missioned to kill these creatures. But as King finds himself drawn deeper into the world of "angel" hunters, he begins to realize the organization he works for may be just as malevolent as the creatures they claim to fight.

Fun. Evil. Dress appropriately.
