While driving a Jeep through the desert of Yemen, Robert Bradin, who is the brother of the driver Diane Bradin, shows a pack of marijuana to her and she immediately tells him to get rid of the bag. However, they are stopped by two military vehicles and arrested. Foster and Loker are hired by the US government to negotiate the release of the siblings in a short period since they will be executed for possession of drugs. Foster uses her knowledge and culture to negotiate with the Yeman representatives while she uncovers secrets about the relationship of Diane with the government. Meanwhile, Dr. Jeffrey Buchnan, who is one of Cal's best friends, arrives to his office to hire Cal to find who has stolen the formula of the Priox from the Laboratory Ribocore since there is a cheaper version in the market that is killing people causing strokes. Cal has no difficulty to find the spy, but the chemist discloses that the formula is identical and Priox is causing the stroke as side effect. Now Dr. Lightman questions whether his best friend is lying or not.
"The Best Policy" is another interesting episode of "Lie to Me". The plot of the siblings in Yemen shows an idiot that brings marijuana to a country with rigid law. The guy has to be too stupid to ignore the dangers of this attitude. The knowledge of Dr. Foster is amazing finding who really had the power to negotiate in a different culture. The plot of the pharmaceutical industry shows the damages that this segment causes to the population intentionally, based on the ambition of his directors. My vote is eight.
