The Daytime Representative.

The seasoned vampire Count Darlak returns to his castle after a century-long absence. He has a wonderful appetite, and soon people start disappearing and dying. And only the count's servant, a man named Adam, remains alive and well. Although his only desire... is to become a vampire himself. Adam is a shipwreck victim. At one time, the count picked him up on the seashore, cured him and made him his “day representative.” Adam is an obedient tool in the hands of evil, but any tool can one day get out of control.
