Jekyll and Hyde - Season 1 (2015)

Garson discovers something about the curse of the Jekyll family that could hold the secret to saving Maggie's life. Dance sets his trap, tempting Robert with an offer of help - but Bulstrode disrupts their meeting.

After curing Maggie, Robert learns that there is a distant branch of his family, the Jezequiels, living in an isolated house in Suffolk and, with Max in tow, decides to visit, learning from locals about a monstrous black dog which terrorizes the area. Robert is mistrustful of the widowed Renata Jezequiel, whose husband was apparently killed by the creature and whose student son Brant has disappeared. He believes she is a shape shifter working for Tenebrae who transforms herself into the black dog. He must use his own powers of alteration to expose the family's secret ...

Tormented by recent tragedies Robert loses control of his transformations. Bulstrode reveals he has Ravi and enlists Robert to track down Spring-Heeled Jack.

Robert and Ravi go in search of the parasite-infested Spring-Heeled Jack. Robert then faces a race against time when this Reaper takes control of Ravi.

Robert is unable to resist the temptation to track down the monster that is killing wealthy young men. When he corners the killer she tells him two stunning pieces of news.

Robert, Ravi and Olalla take Maggie to the safety of Renata's house, but Ravi is rightly uneasy as the corpse of Renata's supposedly dead husband Gideon has been inhabited by an escaped incubus, a demon which sucks the life out of others and takes on their form - and Tenebrae are also after it. Renata and Robert both have near fatal encounters with it before Renata explains that her house is a portal to a demonic kingdom ruled by Lord Trash, from which the incubus escaped. Robert does battle with the monster, seemingly killing it before Renata informs him of the calyx...

Returning to London Robert's group is waylaid by Fedora and her thugs, who steal the incubus, but they are rescued by Garson, Bella and Hils, whom Olalla has contacted. With the incubus in her possession Fedora is able to fully revive Dance but Robert, having learnt Lily's secret, is not best disposed to help MIO until his friends convince him that Dance threatens global security. Tenebrae launches an attack on Bulstrode's headquarters, stealing the all-important Calyx, before arriving at Robert's house for a final, deadly showdown.
