Filmmaker Mehran Tamadon (Bassidji) is an Iranian in exile, living in France. For years, he was able to travel back and forth between the two countries. Then, in 2012, he was warned that coming back would mean prison, torture, or worse.
Seeking to understand the mindset of the torturers, and the experience of fellow emigrés who have suffered at their hands, Mehran comes up with a plan: He'll ask one of them to interrogate him, pushing him to the limit. Celebrated actress Zar Amir Ebrahimi (Holy Spider) takes up the offer. She interrogates Mehran over two intense days - stripping him almost naked, subjecting him to freezing showers, haranguing him about his beliefs.
But as MY WORST ENEMY progresses, it raises uncomfortable questions for everyone involved.
What long-term effects will Zar suffer from taking on the vile persona of those who once tortured her? How much of Zar's interrogation is a performance? A role like so many others she has played? Is Mehran being tortured, or is he the torturer for putting her through this?
