It is 1939. In the Soviet Union, Stalin has placed his hopes on a 30-ton steel monster, known as the RED COFFIN. But the design is not yet complete. And when the weapon's secretive and eccentric architect is found murdered, Stalin sends for Pekkala, his most trusted investigator. He is convinced that a sinister group called the White Guild intends to bring about a German invasion before the RED COFFIN is ready. While engineers struggle to complete the design of the tank, Pekkala must expose plans to propel Germany and Russia into conflict.
