"Citizen X" is the superbly told true story of the hunt for one of history's worst serial killers. What makes this story even more compelling is where and when it took place; the Soviet Union in the 1980's.

** Mild Spoilers **

Viktor Burakov (magnificently played by Stephen Rea) is a newly promoted forensic investigator for the Rostov oblast militia. He discovers past and present unsolved murders, apparently by the same person. The murders are unsolved because no one has ever taken the trouble to properly investigate the evidence. He is driven to find and stop the killer. His only tools are his dedication, skill and honesty. His obstacles are the corruption and political ideology of the Soviet system that discourages the search for truth. His naiveté would have led to failure were it not for his boss, Col. Mikhail Fetisov (Donald Sutherland). Fetisov is a politically astute cynic who understands the game and knows how to deal with the Soviet bureaucracy. However, he also shares Burakov's desire to bring a murderer to justice, even if the official party line is "There are no serial killers in the Soviet Union!"

The cast is outstanding. The locations and sets are perfect recreations of latter day Soviet life. Randy Edelman's score is particularly good.

More important, this film shows a dark and disturbing criminal phenomenon with both intensity and poignancy. This was a made-for-cable movie by HBO Films and they have become a great resource for films that would otherwise never be made.
