Berlin red (Main)

April, 1945. East of Berlin, the Red Army stands poised to unleash its final assault upon the ruined capital of Hitler's Thousand Year Reich.

To the north, at a lonely outpost near the Baltic sea, German scientists perfect a guidance system for the mighty V2 rocket.

This device, known only by the codename Diamondstream, will allow the rocket to arrive at its target with pin-point accuracy.

When a radio message sent to Hitler's headquarters, heralding the success of Diamondstream, is intercepted by an English listening station, British Intelligence orders one of its last agents operating in Berlin to acquire the plans for the device.

Desperate to evacuate their agent from the doomed city before the Red Army swarms through its streets, British Special Operations turns to the Kremlin for help.

They ask for one man in particular - Inspector Pekkala.
