“The cedar under the water” is the 6th feature film by Mohammad Ali Bashe Ahangar based on a script by himself and Hamed Bashe Ahangar. He is one of the few filmmakers who still make the film about holy defense and heroes. He tries to portray the consequences of this war on society and people over the years dramatically. His new narration of war is focused on two Iranian families with two different ethnics and religions that try to own the martyr. The encounter of these two families is one of the most memorable ones beyond any boundary. They are opposed each other by the right need to reach out empathy. The film has a special foundation for this encounter by following a soldier of Meraaj With a personal theory; he intends to play a role in determining the fate of the anonymous martyrs. He tells the story from his point of view and his special worldview. The film becomes more attractive when he is supposed to experience the violation of his theory by a critical experiment and he reach to credible change in a step by step path.
