text: 24: Day 7 Tony is discovered to be alive and currently working with a terrorist group to disrupt US President Allison Taylor's invasion of Sangala by blackmailing her with terrorist attacks. It is ultimately revealed that Christopher Henderson purposely missed Tony's heart when he stabbed him, and planned on turning him. He had his people take Tony's body, and they were able to revive him within 10 minutes of his apparent death. Jack Bauer and the FBI apprehend Tony. Jack requests to interrogate Tony, but fails to get him to talk. However, during the interrogation, Tony taunts Jack into attacking him and while they fight, Tony is able to discreetly give Jack the code word 'Deep Sky'. Jack recognizes this as an old CTU code for a phone number, which he calls once he is in private. The number leads him to Bill Buchanan and Chloe O'Brian who reveal that Tony was working undercover for them to uncover corrupt US officials working with General Benjamin Juma, the dictator of Sangala and perpetrator of mass genocide. Furthermore, Tony needs to be freed so he can continue his work. Jack breaks Tony out of FBI custody and joins him, Bill and Chloe in resuming their independent operation, which culminates in the elimination of the terrorist group, the unmasking of Juma's allies in the U.S. government, and the deaths of General Juma and his squad of soldiers who storm the White House.
  Following the end of the White House siege, Jack and Tony scramble to intercept and then recover a shipment of bioweapons engineered by Jonas Hodges, president of mercenary corporation Starkwood, who intends to blackmail the President and enact Executive legislation benefitting himself. Aided by the FBI, Jack and Tony successfully destroy the chemical weapons in the Starkwood compound, although Jack is exposed to the bio-weapon and infected.
