Michael Valentine is sick of sitting in one place. A professional of his level needs risk, a boil of adrenaline in the blood and an indescribable feeling of victory over a strong opponent, without whom life seems empty. Upon learning that an exhibition of precious stones was opening in Miami, he immediately recalls the "yellow Austrian" diamond. From this moment a new stage of life begins. The sale of the diamond was a certain risk, but Michael could not expect that he would be dragged into a whirl of deadly adventures that made the operative remember his professional skills.
