Spurred into action, Michael strides across the party, looking purposefully at a guy with a briefcase. He doesn't get very far before he's grabbed by a couple of goons. See, this is why I hate going to parties. I'm always afraid there will be goons. KITT helpfully tells us that there are four armed men. Michael is dragged through an "Authorized Personnel Only" door, and we hear the sound of punching. And then Michael walks back through the door! See, you thought he was being beat up, but really he was beating up those goons. It's a classic bit of misdirection. I did it just a few paragraphs ago myself, with that whole Whiz Kids thing. I'll shut up about that now.
Michael gets KITT to tell him how to get to Sarah, and they have some banter involving the phrase "keep your eyes peeled". You know how that one goes, I'm sure. Because KITT doesn't have eyes, which means that phrase is hilariously inappropriate. Oh, mercy. There's more banter, in which KITT tells Michael he could be running through the stairwell faster if he ate a healthy breakfast and didn't drink and canoodle so much. As Michael gets closer to wherever Sarah is, KITT further establishes that the armed men are not consulate guards and may well be after the same package that Michael's trying to find. Michael deduces that since they don't have the package, they must be after the files (remember, there are two things: the files and the package), and since Sarah has the files, they must have Sarah.
And indeed "they" do, although we already knew that. They're still menacing her with some suspicious yellow-green stuff in a hypo. The head goon taunts Sarah a bit and repeatedly asks her where Mike Traceur is. KITT reports to Michael that Sarah's heart rate is jumping, and also that Michael has turned in the wrong direction. I'm not entirely sure how KITT knows Michael's exact location inside the building. Maybe he has a super-accurate GPS or something.
Suddenly! KITT is surrounded out in the parking lot! Michael is still running through corridors! He finally picks a lock and busts into a parking lot where two guys with guns don't look happy to see him. He quickly takes them both down while KITT goes into ATTACK MODE. This turns out to involve a lot of Transformers-style CGI and engine-vrooming. The thugs open fire, which causes a CSI-cam going into the insides of KITT, where fancy high-tech things happen. Turbo Boost activates, which, as you'll remember from the original show, means that KITT flies through the air for about twenty feet. Except this is the 21st century, so now there's more blue neon. Anyway, this is sufficient to baffle the gun-toting thugs. Michael finishes off his goons, then busts into the vault when they unwisely open the door to look outside. Two more goon-disposals later, he's alone with the Head Good, the Hypo of Green Stuff, and Sarah. Sarah finally gets up and kicks the stuffing out of the Head Goon, but ruins it a bit by complaining about being afraid of needles.
