Grace’s life has been a series of disappointments. Addicted to morphine, the nurse (Anna Hindman) doesn’t have much reason to fight back when Evienne (Chloe Carroll), a vampire, kidnaps her. Deep below Philadelphia, Evienne has preyed on the city for eighty years from a series of forgotten subway tunnels. Now, with her still-human son Henry (Robert Picardo) dying of cancer, Evienne has nowhere to turn for help but from the innocents who are normally nothing more than dinner. Grace and Evienne develop a strange bond that caring for the same person creates, or is the vampire just beguiling the nurse, twisting reality, and lowering her inhibitions? However, more than one vampire curses the streets of Philadelphia. Evienne’s spurned ex-girlfriend Tempest (Sam Rothermel) has returned full of bloodlust and vengeance and wants nothing more than to draw Evienne away from what little humanity she has left. As Evienne ushers Grace into her secret life as the world’s apex predator, the mounting bone-dry body count soon draws the pursuit of Dayanara (Telita Perry), vigilante vampire slayer. But does Grace even want to be rescued? The undead life offers her more control than she could ever attain as a human but her patient, who has studied his mother his whole life, begs Grace not to become just like her, a monster.
