Tarik learns hat his partner co-coaches a program to rehabilitate former prostitutes when she recognizes former charge Marina Petrowa, who was beaten into hospital wearing a fake cop uniform, actually dumped with the trash to die. *She worked in the illegal escort-service run by Russian Galina Sorokina, an emigrated survivor of the Siberian clan Urki, eradicated in Russia under Putin, known for its pathological Ortodox piety mixed with sadistic cruelty. With Wolle researching the Urki and Mates joining the field research, they concentrate on escort Tatjana Nikiforowa and her ambitious 'driver-protector' and lover Boris Memedow, who has his own dangerous plans.
