So, the Chinese want Jack to steal some chip from the suitcase nuke which will give them access to Russian defense technology. Jack agrees, but needs Chloe's help. Morris figures out what she is doing and makes her tell Bill.
Mike arrests Jack. Bill talks to Jack, and then calls the President, who gives Jack permission to go through with the plan, as long as Jack can guarantee that the chip will not fall into Chinese hands. Jack says he will blow himself up if it comes down to it. Jack finally pulls the "you owe me" card, by saying that the President was willing to have Jack killed in order to stop Fayed, which Jack did not argue against.
As Jack and Mike go to meet the Chinese, President Palmer collapses and has a cerebral hemorrhage, leaving him incapable of leading the country. VP Daniels takes over and his first act is to nix the mission.
Bill calls Mike, but Jack knows something is up and pulls a gun on Mike. He kicks him out of the truck and goes off on his own. Mike tells Jack that he cannot fight the White House, I guess Mike has not read Jack's file. Jack always goes against Presidential orders, and he always wins. Hell, Jack took down a President last season, let's be honest here. Jack will do whatever it takes to defeat anyone.
Jack did not kill anyone, but he says that he will kill Chang before it is over. I guess next week he kills 3 people.
