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.

Galvin lets his emotions get the better of him when his wife's murderer, Mr Tibbs, arrives in town. Hell-bent on revenge and with no regard for his own safety, Galvin arms himself to the teeth and embarks on what amounts to little more than a suicide mission.

The problem is, his thirst for vengeance leads him straight into rat-man's trap, putting more than his own life at risk.

When a bad boy vampire arrives on the scene and Mina starts behaving strangely, Galvin gets suspicious. Mina confesses that Quincey is back. He has come for her – he wants her to give in to her half-blood heritage. Galvin reassures her that he, of all people, understands – but they both know that sentiment has no place in the smiting game. One thing’s for sure - a battle of epic proportions is in the offing…

Mina and Galvin's investigation of a murder lead them to believe that Luke is in danger. Whilst Luke is lying low Mina starts having visions of a winged beast; Galvin and Ruby are concerned that Luke's new love interest is a low life who had taken the form of a beautiful female to trick its prey.

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.
