The Flat (2011)

When Arnon Goldfinger's grandmother dies in Tel Aviv, his whole family comes for the necessary disposition of her property. While dealing with all the stuff, Arnon makes a shocking discovery: evidence that his German Jewish grandparents had a long-lasting friendship with senior Nazi SS officer Leopold von Mildenstein before and after World War II. His repulsion and confusion at how his beloved grandparents could have done that sends Arnon on an international search for the truth. In doing so, Arnon learns about a complex relationship in which family, sentiment, history, and human nature combine to produce a kind of denial in reaction to the worst of reality.
