Demonium (2001)
Rasmus Bentley and his lover, Maria, are quickly climbing the ladder of
success. One afternoon, after the closure of a deal which will secure
their lives together forever, a terrible turn of events occurs. One year
earlier, an eccentric scientist is brutally murdered in his sprawling
ancient castle. His notary, Rasmus, calls together the man's heirs listed
in his will, but as they all gather at the castle, they fail to realize that
the murderer is still haunting the ancient halls. One by one, the group is
methodically hunted down by the lunatic, whose vicious bloodbath is far from
complete... The fates of Rasmus and Maria have been foretold, but how did
this madness begin? (IMDB) NV
