Grazyna Szapolowska's husband dies. He was a public defender, so she tries to arrange for his last client, Artur Barcis, to have a good defendant. She arranges for Aleksander Bardini, under whom her husband had apprenticed, to take the case. Barcis is accused of having led an illegal strike, and Bardini works to have him tread the middle ground of confessing and denial.
Krzysztof Kieslowski's movie is a murky one that tells us we can never tell what is going on at the moment. Only in retrospect can we figure out what was going on, and even that may not be true. It is a gloomy movie, with a lot of motivation left unclear. Did Miss Szapolowska really love her husband? Why has Bardini, who hasn't taken a case of this sort for more than 30 years, taken this one? What was the strike actually about? That remains uncertain, even after the movie's end.
