Luke Rutherford is your average teenager – until his dead father's best friend, Rupert Galvin, turns up. Galvin has come to tell Luke his secret destiny: he's the real-life great-grandson of Abraham Van Helsing, the vampire hunter in Bram Stoker's Dracula. Luke is set to inherit the family mantle as a warrior against the supernatural entities swarming the earth.

Unfortunately, powerful Half-Life, Gladiolus Thrip (Mackenzie Crook) is standing in his way.

Luke becomes haunted by dreams about the car crash that killed his father and Galvin's connection to it. A visit to a psychic convinces him his godfather is not the man he seems and, with Gladiolus Thrip back on the scene and showing an unhealthy interest in Luke's past, the vampire-fighting duo look set to be torn apart.
