Charlie Kale knows life isn't easy. But for the first time, this truck driver might have finally found her little piece of happiness. She's got it all—her big rig, friends, a great mentor, and a man about to join her on the road. That is, until the good things in Charlie's life all fall apart, and she finds herself at the mercy of a sexy but mysterious gunman who claims to be a member of a secret order dedicated to fighting the supernatural monsters that filter over into our world. She's given a choice—join up or die, and while the gunman might be insane, Charlie's hell-bent on not dying. Too bad it looks like that might not be an option.
