In the batch, it is necessary to urgently evaluate the area where the sample contains an increased gold content. But how easy it is to go through the route, collect samples and look at them. And how difficult it is to draw a conclusion: what to expect from the site if there is ore here, and if there is, what kind and how much. Everyone has doubts, but they do the work, gather evidence of their own version. And not far from the party and the miners’ village, in the event of an accident with a cash-in-transit vehicle, the wages of the workers of the entire village disappear. Moreover, the accident was staged, which is impossible if the criminals were not warned about the planned transportation of money. Yura, the eldest of the geologists, with his friend mechanic Evdokim, joins in the search for criminals and stolen money. At first, there are results: a cache with buried bandits’ clothing was found. But after a couple of days, two of them die in a shootout with the checkpoint soldiers, and only one survives, who is with a motorcycle and whom no one has seen. And how our heroes used the stolen money, what adventures they had, and who turned out to be the leader of the gang - this is in the book.
