The famous Russian Journalist Ilya Ilaev has recently been in a strange state for him, which can be called depression. On the strong recommendation of his friend and colleague Sergei Khronov, he is going on vacation to regain his strength and regain his former confidence. The owner of the publication, Vsevolod Rebolarov, suggests combining a vacation with a simple work assignment. Ilaev will have to collect information about the “Book of Life” that mysteriously disappeared from the excavation site. The ancient manuscript written by Avicenna has been a long-standing subject of debate among world historians, and according to one version contains the secret of immortality. The longer Ilya investigates, the more convinced he becomes that Rebolarov’s request is not a trivial task at all. He realizes that he is involved in a game whose rules are not yet accessible to his understanding. Almost everyone who had information about the “Book of Life” turns out to be dead. A brutal hunt begins for financial corporations and the world's largest religious denominations for the mysterious manuscript.
