THE RUSSIAN PRIME MINISTER HAS BEEN ASSASSINATED. THE WORLD STANDS ON THE BRINK OF WAR.

Russia accuses the United States of assassinating their Prime Minister in Hanoi, naming Delta Force member Sergeant Carl “Niner” Sung as the assassin.

It is a desperate race against time as the innocent involved are hunted down without mercy. Facing impossible odds in a country where they have no friends and no hope of rescue, they stand alone.
