The Vampire Family (1990)

Originaltitel: Семья вурдалаков

A newspaper sends a young reporter into the Russian countryside to make a nice, sensationalist yarn out of some strange stories going around. Once in the countryside, Igor is accommodated by a peasant family living in the middle of nowhere close to a ruined church. The family is convinced that their dead patriarch will return from the dead as a blood-drinking fiend exactly nine and a half days after his demise.
