Over the last 11 weeks before Day 6, the United States has been targeted coast-to-coast in a series of suicide bombings. A man named Abu Fayed agrees to give the U.S. the location of Hamri Al-Assad, the supposed terrorist mastermind of these attacks, in exchange for former CTU Agent Jack Bauer with whom he has a personal grudge. As a result, President Wayne Palmer has negotiated the release of Bauer, who was illegally captured by Chinese government agents, under "high-price" terms. Season 6 can be divided into two main acts: Jack is released from the Chinese prison, and works with CTU to take down suitcase nuke-armed terrorists, and discovers links to his own family in the process. After the nukes are recovered, the Chinese manipulate Jack into giving them one of the circuit boards, elevating tensions between the United States and Russia. Karen Hayes clashes with Tom Lennox over the ethics of suspending civil liberties for Muslim Americans. Corrupt members of Wayne Palmer's administration attempt to have him killed so that they can take more extreme measures to find the nukes. Jack discovers that his father and brother both conspired with Charles Logan during the nerve gas crisis. Milo Pressman develops feelings for his boss Nadia Yassir and becomes alarmed at the way CTU agent Mike Doyle treats her. Morris O'Brian struggles with the guilt he feels over giving Fayed a working detonator and almost relapses into alcoholism. Jack becomes attached to his nephew Josh and insists that losing him as collateral damage is not acceptable. Jack struggles with the fact that Audrey has been tortured by the Chinese and will need long term care.
