The Shabanovites manage to remove a batch of diamonds worth several million dollars from the storage facility and escape unhindered. But the luck ends there. Soon one of the gang members is arrested, and a hunt begins for the rest. In addition, the bandits are accused of stealing diamonds worth not millions, but billions of dollars. But why?
