On September 22, 1998, the Iranian poet Hamid Hajizadeh and his nine-year-old son Karun, whose name symbolically refers to Iran's longest river, were brutally murdered in their home in Kerman. The documentary film, based on the statements of the survivors, tries to sensitively reconstruct one of the many terrible motivated events that took place in Iran at the end of the previous century and draws us into the fateful day with the help of detailed shots of the objects in Hamid's study.
