Spanish with english subtitles: the best description I could find was

"Un rico hombre de negocios se casa con una joven y deciden ir en viaje de luna de miel a Transilvania, ciudad natal del empresario, para visitar las tumbas de sus padres. Cuando la pareja va al cementerio es asaltada por unos bandidos y él es asesinado."

Which is (roughly) "A rich businessman lives with a young person and decides to go on a honeymoon trip to Transylvania, the home of the businessman, to visit the parent's tombs . When the pair goes to the cemetery they are assaulted by bandits and he is killed"
