A major national security incident occurs when the firewall responsible for protecting America's government computer
infrastructure is breached. It will also feature the show's first female president, Allison Taylor,
played by Cherry Jones. It is thought that this will be the first season not to feature CTU, because
it appears to have been disbanded by the U.S. government at some point after the events of Season 6. It also appears that
Tony Almeida will be returning to appear as the main antagonist of season seven, despite being previously thought to be deceased.
