Synopsis:
On a seemingly normal night in Boston, a satanic ritual is taking place: a bride is to be offered up as a sacrifice. However, Dracula, the King of Vampires, swoops in and steals her, with the intent of depriving the woman of both her blood and her life. And yet, despite his earlier motives for abducting the bride, Dracula is astonished by her beauty and decides to keep the woman as his wife. 

He and Domini, his spouse, lead a fruitful life together, bearing a healthy son by the name of Janus, with Dracula's crime against Satan fading from memory. On the other hand, Satan hasn't forgiven him for stealing his rightful bride and is plotting to ruin his happiness when the time is right. Another group, the Vampire Hunters, similarly wish to destroy Dracula as vengeance for the souls he has taken to feed himself. 

Now carrying the burden of a family, Dracula must protect himself from Satan's plots as well as from the vengeful Vampire Hunters in a desperate fight for survival and forbidden love.
