Pinchas Gutter has returned to Majdanek at least a dozen times, but this trip is his final one to the onetime Nazi concentration camp. His first was one he was 11, when he was taken to Majdanek; now he’s 85 years old, and this is the last time he’ll come here to tell people what the Nazis did to his family. As he rides up to the shuttered camp in the backseat of a chauffeured sedan, he talks about why he’s told his story so many times.

A twisty, protracted fight for justice is deftly traced in “Finding Oscar,” an absorbing, if grim, documentary from producer-director Ryan Suffern (who co-wrote with Mark Monroe) and executive producer Steven Spielberg.

In the spring of 2011, David Benson, found himself walking with his grandmother, Holocaust survivor Sidonia Lax, down the “black path” that once led to the crematorium at the Majdanek concentration camp in Poland. It was Lax’s fifth trip with the annual International March of the Living as a survivor, with the Builders of Jewish Education (BJE) teen delegation, his first as part of a large family contingent with the BJE Los Angeles adult group.
