Psychopathic serial killer Zito, an evil genius whom Mac helped arrest and convict, is up for parole due to gullible psychologist Marion Skinner. Mac testimony, a sharp analysis, prevents his release, but the court appearance allowed Zito to steal a pen and escape, fatally stabbing two staff members. He also leaves a complex series of arithmetic riddle clues. Each points to a place or victim, part of an elaborate trap to teach MacGyver a master class in evil, but unlike the police, Mac proves at least as smart. Written by KGF Vissers

Did You Know?


The angle of the sun does not match in the exterior/interior shots of Mac's houseboat when the police arrive. The first shot of them going in shows the sun at their backs and the interior of the houseboat in the dark as Mac and Lt. Murphy open the front door, yet when they go inside and find Pete tied up, the sunlight is coming in from the back windows, flooding the room and the inside front wall with light. See more »

MacGyver: I just call it as I see it.
Dr. Zito: I'm an expert on the subject. One day I'll educate you.

It's a great episode
30 December 2013 | by (United States) – See all my reviews

I have to disagree with the former poster about the plot holes in this episode. Yes, it is somewhat cliché and the numbers coincidentally corresponding to important things and also spelling out doctor is a bit much, but each time I watch this episode it is like watching a thriller-- of course we know how it will end but we don't know what tricks Zito has up his sleeve for the various protagonists. So love this episode, love the character of Zito, not as much as Murdoc, but just the same he's a great villain--would love to see s showdown with Murdoc, Zito and Macgyver--that would be pretty cool! Mac uses his wits to outwit Zito by getting in his head thinking what he would do, and he does a great job--yes, the script says certain things that they have to abide by, but still a really great episode, which is why the average rating is a 9 out of 10.
