Danielle, Marla's vampiric girlfriend, has been kidnapped, and Marla wants to set her free. Thankfully Marla has her sister, Katrina: Vampire Hunter, to help. But rescuing Danielle is going to be no easy task. Her kidnapper, Vincent, has locked her away in a fortress. Marla and Katrina are only human, but they will do whatever it takes to get Danielle free, even if it means enlisting the help of murderous vampires themselves.
