Episode list

01 "They Bite" Luke Rutherford is an average teenager - until his dead father's best friend, Rupert Galvin, enters his life, and a small hideous creature attacks him. Galvin has come to tell Luke that he is the great-grandson of the legendary Abraham Van Helsing. Luke's destiny is to fight against the supernatural entities swarming the earth after he fights a small demon. But half-life Gladiolus Thrip (Mackenzie Crook) has discovered Luke's secret as well. He kidnaps Ruby, imprisoning her in a tomb and gagging her with duct tape, before his apparent destruction.

02 "The Whole Enchilada" Galvin thinks that a girl's disappearance is down to the ancient demon, Gilgamel, a fear confirmed by the priest Father Simeon (Richard Wilson). Gilgamel feasts on innocent souls, whilst masquerading as an angel. As more and more children disappear at the hands of the demon, which is impersonating the first girl who was taken, including Ruby's younger brother, Galvin Luke decide to summon the demon in order to defeat it. Using a magic sword he defeats the demon just before it feasts.

03 "Saving Grace" The return of Galvin's wife's murderer, Tobias Tibbs (Kevin McNally), a half-life who likes to experiment on humans, sets the vampire hunter on a path of vengeance. This leads to Galvin breaking into Tibbs' lair and having to be rescued from a group of half-lives. Thirst for revenge still not quenched, he and Luke find themselves walking into a trap. Ruby finds herself in a race against time to defuse a bomb placed in the Stacks by Tibbs due to a woman he was experimenting on letting him into the Vault, and with the help of Mina, must find Luke and Galvin before they succumb to a watery fate.

Finally she drinks blood, enabling her to briefly see and kill Quincey.

05 "Smitten" A strange murder in the capital raises fears for Luke's safety, providing him with the opportunity to lie low and taste the life of an ordinary teenager. However, alarm bells ring when Galvin and Ruby suspect the adolescent's new love interest is an entity that can take the form of a female to stalk its prey, and she wants revenge for the death of her two sisters. Luke refuses to believe them, and tells Galvin that he shouldn't let his feelings waiver his judgement just because his wife was killed by a half-life. However, the tables turn and Luke spots Alice hiding a body in her apartment. Confronting her as well as Galvin and the rest of the team, they defeat the harpee.
