The Path in the Abyss‪.‬

After a long flight, the crew of the "Wanderer" starship lands on the planet Firmness, where some of the earthlings are captured, while others manage to escape and settle in a new society for them, posing as local residents. Meanwhile, the caste of bankers-supplying begins to implement a plan to destroy and reduce the Black castes, using the forces of the Officer caste for this. But instead of becoming executioners for their people, battalions of Officers enter the capital and exterminate the Banker caste. Against the background of unfolding events, earthlings are trying to make a desperate attempt to escape from the planet. In this they are assisted by a police officer and an officer of the department of inquiry.
