A skull in a discrete grave is identified as Eugen 'Shenja' Kremer, who was 18 in 1994, when his family and thousands of Russian emigrated form post-Soviet Kazachstan to the GDR. The teen never settled properly and dreamed of a Kazachstan return, which he hoped to finance by robbery with no-good mate Viktor Delwig, but went missing himself. The team also digs into his family, where model big brother Alexander was frustrated father Waldemar's unworthy favorite got away with anything without learning. Henrik Mertens gets even closer to prosecutor Viktoria Nissen, section chief Dr. Lehberger looks ever more suspect of a terrorist-linked past and ends up under IA .investigation.
