Mac has been mistaken for him. One episode case, by the looks of it. Someone is killing off people named "Mac Taylor". So far, at least two Mac Taylor's have been killed, and there are a lot more in within 50 miles of NY. This episode features 4 others then the Mac we know. From the looks of it, the Mac Taylor the killer is looking for has done something to the killer, who is now seeking revenge. The only Mac's affected are the ones who own vehicles. Is it the Mac Taylor that was in a hit and run? Was it the one who dented a vehicle and didn't leave the insurance info? So on and so forth, the clues have lead to the fact that something happened with a Mac Taylor with a vehicle. Which is the real Mac Taylor that the killer is looking for? What did MT do to bring about such revenge? And how will our Mac stop him before it's too late?
There is a nice little scene at the end with Adam and Stella, which involves going for pizza. And the little tidbit that Adam lives in Brooklyn.
