On 17-year-old Kate's last weekend in town, she and her friends plan to spend it together at SpaceCON– the local science fiction convention they attend every year. At the convention Kate meets Paul, a recently turned teen-vampire (who is also dressed as one). But when Kate tries to make a move on him, he accidentally bites her in the neck. Kate and her friends soon discover Paul is not the only vampire at the convention, and it is up to them to stop the vampires and find a way to turn Kate back before it is too late.

While visiting his ailing blind grandfather, young Charlie Mason and his friend, Anne discover a dark secret from the past.
