The article is based on a documentary film What is that in the human being subject of which is a study trip through places of cultural trauma; mass murders, genocide, concentration camps and (non) memorial places, in Croatia and Bosnia and Herzegovina. The work and documentary film examine history and the impact of the history on the present and the future. Filming a student trip plays with different perceptions of reality and the fragility and debatable nature of human knowledge as shown through the film. The entire project studies two segments of history: the events themselves and the processes of learning about them. It explores the impact of war events on future populations and how much politics influences the accepted narrative. The first part examines the true backgrounds of former concentration camp prisoners through their testimonies, combined with statements from expert guides on site, as well as professors, mentors, and guests who question the truth by probing different perspectives of the same event. Mentors attempt to bring students closer to the event while simultaneously distancing them from emotions and encouraging scientific thinking about cultural trauma. The second part focuses on the students' reactions, comments, behaviors, and thoughts about the events presented to them in an emotional manner, unlike the safety of the classroom they are used to. Their reflections are what distinguish this film from other war documentaries. There is also a third insight into the film, which is the impact of cultural trauma through secondary traumatization on students unaccustomed to such presentations and immersion in the center of events. In conclusion, the work examines how influential this form of learning is and whether it leaves potential for continued learning about war through experiential action.
