It was a nice summer vacation in an old mansion with Katarina Kopeikina, her restless mother-in-law Rosalia and their pets! Sometimes ghosts wander around the huge house at night and scare you until you faint. Then unknown spiteful critics bluntly suggest that we go home. And soon, apparently for a special impression, otherworldly forces got down to business: two people were killed in a neighboring village. Haha, that's not the one they attacked! Katarina Kopeikina will expose all enemies and stop any attempts to intimidate her. Just to determine who this mysterious enemy is and what does he want from Katarina?
