Saki's visit to the U.S. takes an odd turn when she meets Takizawa in front of the White House. He's naked and armed with a gun. He has no memory and may be a terrorist. And he's joining her on a flight to Japan.

The beautiful and lethal Sele̤̣o Kuroha enters the picture. Meanwhile, the actions of two wildly different men - a stranger on the street and the Prime Minister of Japan - prove the extent of Takizawa's influence.

After finding out Mr. Outside's true identity, Takizawa learns that those responsible for Careless Monday are planning an even greater attack - but the most disturbing revelation concerns his missing memories.

As missiles fill the skies above Japan once more, Takizawa must rush to prevent a catastrophe far greater than Careless Monday. He has the resources - but does he have enough time?
