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.

Six-year-old Madge might think her sister’s been “taken up to heaven by an angel” but Galvin suspects otherwise. Everything points to half-life involvement and he thinks it’s the perfect project for Luke. A visit to the cadaverous Father Simeon (Richard Wilson) confirms Galvin’s suspicions.

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.

Luke faces his most dangerous demon yet; Mina has a dark secret that may threaten them all.

Mina has a premonition of Luke's death; there may be more than meets the eye to Luke's new love interest.

Luke has nightmares about his father's death; a psychic convinces Luke that Galvin is not who he seems.
