Mentalist Erik Svenson and his medium Eva Brandt specialize in classic ghost summons for private and social occasions. Although Eva seems to have been exhausted for weeks now, Erik drages her from one séance to the next, since their performances have turned out to be a lucrative business. On this evening their job leads them to Jochen Buchholz, who has inherited the house of his grandmother and wants to surprise some of his friends with a true ghost summon. They are skeptical, expect a harmless trick show off and a fun evening. Given the unsettling energies in the house, Eva is increasingly insecure, whether the seance at this strange place is a good idea.
