In order to prevent a war with Russia, the White House orders a trade of Jack’s nephew for the circuit board, and puts Jack in custody so he cannot stop…

Russian ire worries the White House, while the Chinese take on CTU, and the damaged circuit board is in surprising hands.

Russia presses the White House, while Jack must try to thwart the Chinese and his oldest antagonist simultaneously.

Jack enlists the help of an autistic man in the search for Gredenko, and Sandra Palmer makes a fateful decision.

Jack baits Fayed with Gredenko, while the President faces a challenge to his office.

The Chinese want Jack to give them Russian nuclear technology, and the President wants the Vice President’s resignation.

The search for Gredenko finds Jack hunted inside the Russian Consulate and a former President calling on his ex-wife.

CTU’s satellite tracking system is compromised as a bomb-carrying drone heads toward an unknown city. Meanwhile, US forces prepare for a nuclear retaliation on the Middle East.

The President meets with a known terrorist, while Jack searches for Morris, Fayed seeks a trigger, and Tom Lennox makes a choice.

Jack’s search takes him to the home of an old enemy, while a bomber slips into the White House.
