|rating=5
|genre=Teens, Horror
|summary= Zero Hour has passed. Despite throwing absolutely everything they had into a full on assault on Dracula's forces, the combined might of the supernatural departments failed to destroy the ancient vampire, and he has returned to full strength, ready to strike at humanity with unadulterated violence. Secrecy is no longer an option as the entire world reels from the revelation that vampires are real. Department 19 has been through so much, shaken to its core by secrets, betrayals and losses. With the public eye now firmly upon them, the very fundamentals of the Department come under fire, as issues of morality that have long writhed beneath the surface finally burst to the fore. Jamie, Larissa, Kate and Matt have always found themselves at the centre of the chaos, and despite each struggling with their own demons, their friendship and companionship has helped them survive and even thrive within the department. Humanity's last stand will need them at their very best, will need every force that the supernatural departments of the world can muster, whether it be human, machine, monster or vampire. For failure simply isn't an option when the entire future of humanity is at stake.
