Maleficia(1998)

A family of 19th century nobles, traveling through the woods, comes across a satanic sect that is performing a ritual. Initially attracted by the strange phenomenon, all the members of the family begin to observe the development of the black mass. But they will soon bitterly regret their curiosity because the hooded priests begin to brutally sacrifice girls and through the ritual resurrect a myriad of hungry zombies. The family runs away to avoid being devoured and takes refuge in an old, apparently abandoned manor.
