Freddy Martinez and Cara Simonetti are babysitting Tyler Brown, a six year old. Freddy enjoys tormenting Tyler with stories of werewolves. Freddy hears someone coming through the front door and convinces Tyler that a werewolf is entering the house, but the werewolf is actually just Tyler's parents. Freddy and Cara get paid for babysitting, and they head back to Freddy's house. Freddy and Cara play air hockey in the basement, and Freddy's parents aren't home. Freddy and Cara begin fighting, which results in Freddy bumping into a wooden cabinet. The cabinet falls over revealing a previously hidden door in the basement wall.

The kids open the door, and they find a stone walled tunnel. The kids find a flashlight in the basement, so they decide to explore the tunnel. The two friends find another door, and Freddy opens it. Freddy and Cara are shocked to find a coffin. In order to prove their bravery, the kids open the coffin. They find a strange bottle labeled Vampire Breath. Freddy tries to grab the bottle from Cara, causing her to drop the bottle, which results in the stopper flying out. Sour smelling mist pours out of the bottle. Freddy puts the stopper back in, and he notices something has appeared in the coffin: an elderly, bald man dressed in old fashioned clothes. Suddenly, the man opens his eyes.

The man sits up and reveals himself to be Count Nightwing, a vampire. Count Nightwing complains that he's thirsty. The two kids run back down the tunnel. The kids see the door to the basement slowly close in front of them. The vampire catches Cara. The Count is going to drink Cara's blood until he realizes his fangs are gone. The Count asks for his bottle of Vampire Breath. He says the bottle can take him back to his time. The Count forces the kids to look for the bottle. When they find the bottle, the Count opens it, unleashing a green mist. The vampire quickly disappears, but the kids are startled to find that they aren't in the same room as before. They are now in the room of a castle surrounded by multiple coffins. Cara deduces that Count Nightwing took them back to his time.

The coffins around the kids begin opening, revealing many vampires. Count Nightwing approaches the kids and reveals he doesn't know how to send them home except for by turning them into vampires. Count Nightwing leaves in search of more Vampire Breath. He reveals that vampires must have it to stay alive, and it can bring his fangs back. Cara believes that they need to find the Vampire Breath before the Count. The kids explore the castle. They break a window and crawl onto a ledge with the hope of escaping. Freddy falls, but he is saved by a bat. Once inside, the bat turns back into Count Nightwing. The Count warns them not to try to escape again before leaving again.

Freddy and Cara find a coffin, which they open. They find a bottle of Vampire Breath inside. The two friends are approached by a young looking girl. The girl says that her name is Gwendolyn, and she says that the Count forces her to do work around the castle. Gwendolyn leads the kids down a long tunnel and into the cellar. She stops suddenly and explains that she is actually a vampire, and she is thirsty. Cara suggests that Freddy use the Vampire Breath to transport them to the future. Freddy opens the bottle, but finds that its empty. Count Nightwing approaches. Gwendolyn and Count Nightwing begin hissing at each other, allowing Freddy and Cara to escape. Still in the cellar, the kids finds a shelf filled with Vampire Breath bottles. Count Nightwing finds the kids and says that only one bottle is full. All three begin searching for the bottle.

Freddy says that he found the bottle. Freddy and Cara begin tossing the bottle back and forth, keeping it away from the Count. When the Count retrieves the bottle, he opens it, only to discovers that it is empty. Freddy realizes that he had grabbed the wrong bottle. Freddy grabs another bottle that he thinks is full, and he tosses it to Cara. The Count tries to grab the bottle, but it falls to the floor. Putrid gas pours out. Before long, the kids find themselves back in Freddy's basement. Count Nightwing is frightened to find that he has been transported forward in time with them. Freddy's parents enter the basement, but they don't seem disturbed by the vampire.

Count Nightwing recognizes Freddy's mom, and Mrs. Martinez addresses the Count as her father. She introduces Count Nightwing to Freddy; the Count had slept for so long, that he hadn't met his own grandson. The Count complains that his fangs are gone, but Mrs. Martinez says that his dentures are in a glass in the basement bathroom. Mrs. Martinez retrieves the dentures and hands them to the count. Shocked by all of this news, Freddy asks if he's a vampire. His mother says he is, but his fangs haven't grown in yet. The three adults agree to look for something to drink. They all turn into bats and fly away.

Freddy decides to explore the basement's bathroom further to see if there's anything else strange inside. He finds a bottle labeled as Werewolf Sweat. Freddy accidentally opens the bottle, and a strange liquid pours out onto both Freddy and Cara. Freddy is worried about what the substance will do. Suddenly, he hears Cara beginning to grow

Only a vampire can create another vampire, so logic tells us that the history of vampires begins with a single vampire who created the others. Much like the chicken-and-the-egg argument, we had little insight into how the first vampire came about until recently.

The answer lies in the Scriptures of Delhi, specifically in the collection of writings known as "The Vampire Bible".

The first vampire started out as not a vampire at all, but as a human man named Ambrogio. He was an Italian-born adventurer who fate brought to Delphi, in Greece. in a nutshell, a series of blessings and curses transformed this young man into history's first vampire.

Specifically, it began with the sun god Apollo, who in a fit of rage cursed Ambrogio so that his skin would burn should it ever touch sunlight again. Ambrogio's bad luck followed when he ended up gambling away his soul to Hades, the god of the underworld. The next curse came via Apollo's sister Artemis, the goddess of the moon and hunting, who made it so that Ambrogio's skin would burn if he touched silver.

The blessings came soon after when Artemis, taking pity on the poor young man, gave him the gift of immortality. He would carry his curses - his skin burning by sunlight or silver, but he would live forever in his current form. Not only that, but Artemis also gave him the speed and strength to become a hunter whose skills were second only to her own.

Blood-sucking (which, by the way, is called "hematophagy" in case you were curious) is also included in this "blessing". In the vampire original story, Ambrogio hunts swans and uses their blood as ink to write love poems to his lady Selene. While this may be considered a little creepy by our standards, it wasn't all that unusual in ancient Greece to make do with what you hunted.
