I thought this episode was very average compared to other MacGyver episodes.
MacGyver follows Pete to Northern Russia as Pete believes that Alexander Karsoff, a Russian dissident is dead because of him and Karsoff's daughter, Maria, is also in trouble for conspiracy. MacGyver was never meant to be involved in this mission, but Mac was worried and wants to help.
The opening scene has a bit of action when Pete goes to Maria's cabin in Moscow and finding out that Alex isn't really dead, he is secretly locked up in a mental institution. The secret police turns up and Pete, Maria and MacGyver escape - and a speed boat chase occurs. MacGyver comes up with a plan to tie some rope on a fuel can and jam the other's intake, as it is a jet drive.
They come up with a plan to pretend MacGyver is a mental patient, Pete is his doctor and Maria is from the village helping out. Mac meets a good guy in there named Demetri, who is only political not mental. With the help of Demetri and Lovat, they successfully rescue Karsoff and free him from the institution.
I did enjoy the episode, but didn't think it was one of the best. It was quite funny how relaxed and calm MacGyver was during the final escape... so at ease.
