[English]
Zeca (12) is the eldest of Beto and Livia's three children. Despite his parent's disapproval, he seems to have an inexplicable obsession with vampires and is constantly reading about their stories and surfing the net to find "vampire fans" just like him. His favorite one of all is "Boris", the most powerful vampire that ever existed and who is said to be waiting for his beloved Princess Cecilia to reincarnate and join him through eternity. However, little does Zeca know that Boris also wanted something else more than anything in the world: have a son so he can become a "master vampire" and that he is indeed that son.

When Boris goes in search for his son to join him, he reveals to Zeca the truth about his origin, powers, and that his mother is the reincarnation of the Princess Cecilia he so much loves. To his surprise, Zeca does not accept him and declares a war on his father and anyone who dares threaten his family. However, when his vampire powers start growing, what will he do? Will he join his father Boris so they can together become the "most powerful vampires that ever existed" or will he save his mother from the vampire's magical love bite?
