So Buffy the Vampire Slayer's handler (Anthony Head) was a top MI-5 spy. A flabby middle-aged guy in love with a hot twenty year old enemy spy. He betrays his country, and in the middle of it all the main MI-5 cast are too busy worshipping Anthony Head, to stop him. He runs amuck over all of them.
The team of Danny & Zoe are assigned to maintain surveillance on Anthony Head, but they get arrested by street cops because they are so obvious that the street cops think they are casing houses to burglarize them. Head and his girlfriend get a laugh as they watch the coppers arresting MI-5, and then they escape to plot the assassination of visiting U. S. President Bush.
When Head and his enemy spy team goes to the University that has the Air Traffic Controller database and the geographic map records for the national database, nobody at MI-5 thinks to check that out. The MI-5 crew assume a top spy ring went to the University to steal computer towers that even in 2002 were selling for less than $500 each??
Eventually the brain trust at MI-5 realizes that the U. S. President's plane can be guided to crash, thanks to the Air Traffic Controller database that Anthony Head and his enemy spy team had downloaded.
This episode was very disappointing as to how incompetent the MI-5 team was, and how they got played and outsmarted constantly. Anthony Head ran circles around MI-5, and he did not even need Buffy to help him. At the end of this story, there is a cut to a congratulatory speech about the success of MI-5, yet the previous scene showed that Anthony Head and his spies got away. The conclusion did not make much sense, though at least the President's plane did not get shot down.
