Bite Club takes place in a world where vampires are the immigrant minority, but the specific family of vampires focused upon, the Del Toro's, are also the mob. Following the patriarch of the family's death, the siblings gather to decide who will take his place over the family. Ironically he left it to Leto, the first vampire Catholic priest, who swore off his family. This leads to the usual round of disagreements and betrayals that would be expected in a crime family, and in the end, only one family member will be allowed to live. Survival of the fittest.
