In 1970, three children are born at the height of a total eclipse. Due to the sun and moon blocking Saturn, which controls emotions, they have become heartless killers ten years later, and are able to escape detection because of their youthful and innocent facades. A boy and his teenage sister become endangered when they stumble onto the bloody truth.

Adult film star Jennifer Bond has everything a girl could want: looks, power, a fabulously dangerously sexy boyfriend…and immortality due to the fact she was transformed into a vampire circa 1979. But as her 50th birthday draws near, she returns to the town she left in search of the love of her life, the aging porn director John Welles. Unfortunately, one of her travelling companions and former co-star takes a shine to one of their midnight snacks, a pizza delivery boy, and she creates a new vampire with a taste for bloody revenge! As the four ex-porn stars ravage the town as part of their nightly fun, the pizza boy hooks up with the beleaguered mayor and the Moral Majority to stomp out the dangerously porn star-vampire menace.
