In his project Apparitions Peeters tries to finally figure out what happens after death. Disguised as a spiritist, he travels to the end of the 19th century to infiltrate the lives of prominent scientists and to investigate the fantasies created by popular inventions of that time. Simultaneously, he launches himself towards the end of the 21st century to discover which inventions are being used to bring back the death, and which hard- and software is used to provide ghosts with a bodily presence.
