The Reich’s army is seizing the Caucasus in order to gain access to oil deposits. The Soviet Union sends a tank detachment to defend it, together with a new iron monster, the KV-45, which will be commanded by Major Prokhor. But he hates robots! On their very first mission, the Soviet recruits come under fire. Lyon and Murat survive and learn the real reason for the Germans’ presence in the Caucasus — and it has nothing to do with oil… The disgruntled major, the KV-45, and the recruits will have to escape the trap together, unravel the mystery, and stop the enemy led by the Grosssturmann.
