An ordinary morning in St. Petersburg promised nothing unusual, but for the guard Ivan Bazыkin it turned into an unexpected find—during his rounds he stumbled upon a corpse. The same morning became special for Major Alexey Zubov, who was asked to look into a mysterious announcement about selling a painting by Kazimir Malevich on a marketplace.
Mira Borisova accidentally ended up in the apartment of an old friend of the family, who disappeared without a trace and was then found murdered at the dacha of his former student. These events were only the beginning of a series of strange incidents that Major Zubov will have to investigate with Mira’s support.
