A Polish sewer worker (Robert Wieckiewicz) reluctantly helps Jews hide from the Nazis during the Holocaust—and the people are forced to live without daylight in the sewers for more than a year. Based on the true story of Leopold Socha and the people he helped, the movie is tough to watch. But in the end, the film is rewarding, with Wieckiewicz delivering an absorbing performance, and director Agnieszka Holland doing an excellent job of capturing the claustrophobic conditions. Nominated for a Best Foreign Language Film Oscar, the film is long (nearly 2 1/2 hours), so block out a sufficient amount of time if you plan to watch it. Also, prepare to be emotionally exhausted.
