Yasser Arafat died in 2004 with no confirmed diagnosis, and this Al Jazeera investigation lays out the forensic case built afterward around his personal effects. Scientists at the Institut de Radiophysique in Lausanne test his clothes, toothbrush, and keffiyeh, items stained with his blood, sweat, saliva, and urine, and find abnormal levels of polonium, a radioactive element with a history as a poison. The film walks through the competing explanations that circulated for years, cancer, cirrhosis, even claims of HIV, before laying the polonium findings against them. Paris hospital records, some released here for the first time, are cross-checked against the Swiss lab results. Arafat's widow, Suha, appears pressing the Palestinian Authority to exhume his body from Ramallah so the question can be settled directly rather than argued from residue on a keffiyeh. The film does not deliver a verdict; it shows the evidence a poisoning theory would need, and how much of it is now sitting in a Lausanne lab.
