Beirut, 1974. It is the height of the Cold War. A prominent Yemeni politician is shot dead in his car. Some say, had he lived, Yemen would be a different country today. The killer was never caught, the assassination never investigated.

Political assassinations in the Middle East are almost always unsolved, and reliable evidence can be extremely hard to find. The lack of accountability in these cases is often seen as the reason for the pervasiveness of assassinations in the region. In Yemen, power struggles over the last 60 years have left a long list of murdered political figures. One particular case, the unsolved murder of Yemen’s former foreign minister in 1974, sent shockwaves across the country, and was covered widely in the region and then in the West. Mohamed Noman was a liberal and progressive politician who was building a different path for Yemen, away from authoritarian rule. His death at the early age of 41 had arguably paved the way for decades of military rule in Yemen.

In this documentary, his granddaughter, Mai Noman, sets off on a mission to investigate who could have been behind his murder, almost 50 years after his death.
