Three museum specialists arrive at the manor house - Tomasz, the timid Miss Wierzchon and the perpetually lethargic Bigos. They are to make a catalogue of the valuable artifacts located there and set up a museum. Miss Wierzchon and Bigos want to scare Tomasz into giving up his position as curator. Strange and incredible things happen at the manor. The eccentric tourist Mery holds a spiritualistic seance, a sleepwalker walks on the roof, a White Phantom accompanied by werewolves wanders in the park, Bigos not only falls into lethargy, but also disappears, Masonic treasures are stolen, and the museum workers chase the thieves in Tomasz's bizarre vehicle . .—Arkadiusz
