The plane, which was carrying a huge amount of money to Europe from a small southern country of the near abroad, simply disappeared. It was as if he had disappeared into the air somewhere over the Caucasus. Thus begins a new case for Agent Drongo. The plane can probably be found - although at the cost of desperate battles and many human lives. However, the further Drongo conducts this completely simple, at first glance, investigation, the more clearly he understands that something is wrong, because someone else, someone not connected with the militants, clearly intervened in the hunt for millions. Someone who is still one step ahead of Drongo and his team. But everything depends on this step.
