In the vain of “La Femme Nikita”, "Gabriella" is a gripping story about a darkly beguiling dhampir warrior who was born from a human mother and a vampire father. Gabriella is caught in a world where a war between humans and vampires for the ever dwindling blood supply has nearly wiped out the vampire race. But when the human authorities sentence Gabriella to death as a delinquent, she finds a new identity as an elite warrior when she is rescued by vampires.

The vampire race is far from defeated, and with the help of Gabriella and a cadre of elite warriors, they plan to ensure the survival of their kind in a metropolis of the near future. Gabriella's fate turns when she falls in love with another half-blood vampire - a detective sent to capture her - who has chosen to live in the human world and defend it. Through Gabriella's relationship with one of her own, she discovers that being a dhampir is not a curse, but a choice; and she can ultimately determine her own destiny and use her skills as a warrior in the service of a just cause.
