April 1945. Hitler's Reich is on the verge of extinction, and its enemies are already plotting against each other. Assaulted by Allied bombs and Soviet shells, ruled by Nazis with nothing to lose, Berlin has become the most dangerous place on earth.

Anglo-American journalist John Russell has travelled to Moscow, having escaped from Berlin in 1941 as America entered the war following the attack on Pearl Harbour.

Russell's eighteen-year-old son Paul, born to a German mother, is on the Oder front line, awaiting the final Soviet onslaught, ready to retreat towards Berlin, and resigned to the certain prospect of either death or imprisonment. Inside Berlin, Russell's girlfriend Effi has a Jewish orphan to care for, and the Gestapo on her trail. The advancing Red Army promises liberation, but is also seeking retribution, particularly from German women.

To find and save his son and girlfriend, Russell must reach Berlin no later than the Red Army. But only the Soviets can get him there, and the price of their help will threaten both his and the world's future.
