A Communist agent, Karl Maur, spots Paris on vacation, knocks him out and turns him over to Dr. Tabor, who is a brain specialist and mind control expert. Unable to break Paris, Tabor blanks out Paris' memories and uses an implanted electrode to program him to attack Jim by convincing the disguise expert Jim represents an authority figure, similar to the ones he has lost two women to in the past. Doug and Jim find nothing wrong with him, but Barney finds fingerprints pointing to Maur and Jim delays reporting to the Secretary and tries to find out what's going on with Paris. Paris is befriended by a Communist agent working with Tabor - Tabor murders her and makes it set up as if Jim did it. Paris attacks Jim but snaps out of it when Jim's life is threatened and turns against Tabor.

Toshio Masaki, a powerful anti-American industrialist, kills his sister and frames her husband, an American businessman named Harry Kellem, so as to discredit America and discredit the Economic Council. Paris and Willy enter as a Kabuki artist and a fighter (along with Jim) while Barney and Dana sneak into the grounds and restage the murder as they believe it occurred but with no way of knowing how it ended well enough to convince Musaki. To create a distraction, Willy must engage in a fight with Osaki, Moshio's supposedly-unbeatable champion. Once the film is made Dana tries to blackmail Masaki and then Kellem's daughter Nobu. Paris tips the police to Dana's negotiations with Musaki and they show up as Musaki screens the film as Dana escapes (with Willy's help). Musaki panics and rips the film from the projector before it ends at the spot where the team couldn't recreate him performing the murder, thus confessing his guilt.
