On September 18, 1961, a plane carrying the then United Nations secretary-general Dag Hammarskjöld crashed in Northern Rhodesia (now Zambia), killing everyone on board. With the case still unsolved 50-plus years later, Danish journalist, filmmaker, and provocateur Mads Brügger leads us down an investigative rabbit hole to unearth the truth, as Hammarskjöld’s death turns out to be more than just a simple Cold War-style political assassination. Cold Case Hammarskjöld reveals how sinister geo-political realities could sometimes only be countered by absurdity and irony on a big screen.
