When the caretaker of the state farm “Orlinsk” came to open the old church that had been converted into a storage facility, he found a dead man fallen from a half-ruined dome. There was a pistol in the pocket of his jacket. And so the investigation begins. Who was he? Why had he made his way into the half-ruined church? What in that church was so valuable that he had to break in at the risk of his life?
