From the filmmakers website:
60,000 Palestinian books were systematically looted by the newly born State of Israel during the 1948 war. The story of the stolen books is not only at the heart of our project but also the launching pad of a much bigger and wider endeavor: We intend on communicating the scope and depth of the Palestinian tragedy through the destruction of Palestinian culture in 1948.
Stealing books and erasing a people and a culture. Not exactly light accusations.
