In his search for the Philosophers' Stone which would enable him to understand the mysteries of the production of gold, Professor Dobner goes in search of the notes of alchemist Melchiad Koloman who, according to legend, had uncovered the mystery and produced gold. Dobner becomes acquainted with the Japanese Nakahito and the Indian Fakír Arkaj and inducts them into his plan. The Fakír wants to demonstrate that he can bring a dead person back to life and suggests to his companions that he could attempt to bring Koloman back to life enabling them to ask him directly for the formula. In order to do this he needs a young, healthy male. Nakahito finds a young rake, Marcel, who has squandered away his fortune and now contemplates suicide. At the promise of an easy life for the duration of one year he agrees to commit himself to the experiment.
