A massive data breach threatens the security of every US intelligence operative around the world. With all assets potentially compromised, Mary Pat Foley, Director of National Intelligence, turns to the men of the Campus to track down and stop the Romanian hackers who have put the information up for sale to the highest bidder.

A small mistake in tradecraft by the Campus makes the breach infinitely worse. Now the data is in the hands of the Chinese government, which is using it to block American military force in the South China Sea.

President Jack Ryan is going to have to make some tough choices; some of which may put his own flesh and blood on the firing line.
