Four agents have been betrayed by a mole inside the Agency, leading to their deaths. MacGyver must discover who it is before he becomes the next victim.

MacGyver accepts some East German intelligence in the form of a shotgun shell. The East German police quickly surround him. To distract their dogs, he throws a fowl that his contact shot earlier. His colleague Craig Bannister shows up in another East German police car and whisks him to safety. Back in the LA, a newly promoted Peter Thornton asks his assistance in rooting out an agency mole that has led to the deaths of four top operatives. Mac is reluctant but agrees to help. He is to attend a large conference where Peter will escort Viktoria Tomanova, a defector who might be able to spot communist agents. The keynote speaker, a clergyman, suddenly seems to have trouble giving his speech, pulls out a gun and starts shooting. When he misses Mac and Viktoria, he suddenly has a heart attack and dies. Mac is suspicious, so he attends the autopsy and discovers that the heart is full of fiber-like material plus adipic acid. This tells him that someone could use a magnetic field to cause a heart attack. He talks Viktoria into revisiting the conference venue hoping to draw out the mole. It works. Craig Bannister approaches threatening to kill the pair, he's been conditioned by his wife to follow her directives. She's actually a Soviet operative that Viktoria finally recognizes.—Garon Smith

Mac appreciates fellow agent Craig Bannister's assistance in escaping from the East German police. Recently promoted to director of operations, Peter Thornton insists till vacation-hungry, moving Mac grudgingly accepts helping to root out an agency mole, as four top agents have been eliminated mysteriously. So he puts on a tuxedo to attend, like Craig and his foxy wife Ingrid, a fancy conference, where Pete escorts a likely target, defected Russian scientist Viktoria Tomanova. However it's the clerical keynote speaker who dies from a sudden cardiac crisis, which autopsy shows induced by a magnetic field creating a clutter by creating a fiber-like material from adipic acid. Now Mac and Viktoria set a trap, finding the mole is actually manipulating Craig.—KGF Vissers
