Remember is a psychological thriller that tells the story of Zev Guttman (Plummer), a 90-year-old struggling with dementia and living out his final years in a serene retirement home in New York City. Max Rosenbaum (Landau) befriends Zev in their retirement home after he realises they have something in common: they were both concentration camp survivors who lost their family in World War II to a sadistic Nazi officer named Otto Wallisch.

Immediately after the war, Otto escaped Germany and, as Max divulges, has since been living in North America under an assumed identity all these years. Spurred on by Max (who is unfortunately wheelchair-bound), Zev embarks on a cross-continental road-trip determined to seek out Otto and avenge their families. Do two wrongs make a right?

The film, directed by Atom Egoyan (Chloe, The Sweet Hereafter) includes similarly remarkable performances from Bruno Ganz, Jürgen Prochnow, Heinz Lieven, Henry Cherny and Dean Norris. Christopher Plummer puts on a master class in acting, playing the demanding role of a man who has no subtext because of his dementia.

This tale of vigilante justice parallels a story of the more officially sanctioned justice unfolding in Germany, where a 94-year-old former Schutzstaffel officer named Reinhold Hanning is on trial for his role in the murders of thousands at Auschwitz. As the number of men and women who lived through the Holocaust rapidly dwindles, the themes of memory and justice that the film addresses continue to play out in the real world.
