One Day You’ll Understand (Plus tard), a French film directed by Amos Gitai, starts with Victor Bastien (played by Hippolyte Giradot), baptized as a Catholic, who is searching for a buried past. The film traces Victor’s quest from his childhood discovery of unexplained mementoes in an attic. Finally, his mother Rivka Bastien (played by Jeanne Moreau) outs herself as a survivor of Klaus Barbie’s purge of Jews during World War II to her grandchildren. Occasional flashbacks confuse the continuity during the story, which is based on the recent autobiographical novel by Jérôme Clément.
