It depicts the death of Dag Hammarskjöld in the 1961 Ndola United Nations DC-6 crash and proposes a theory that a white supremacist organization attempted to spread HIV/AIDS among black Africans.

The film investigates the possibility that Hammarskjöld's plane, which crashed in Northern Rhodesia, was shot down by Belgian-British mercenary pilot Jan van Risseghem.

They develop and investigate the theory that a Fouga CM.170 Magister opened fire on the Albertina near Ndola and brought it down, possibly after an attempt to detonate a bomb after take-off had failed in Lubumbashi.

Near Ndola Airport, Brügger and Björkdahl locate what they believe to be the burial site of the wreckage of the Albertina, and they make a comical attempt at excavating it, but are soon stopped by local authorities.

The investigators believe SAIMR to have been a mercenary organization operating by order of MI6 and the CIA, and involved in the Hammarskjöld assassination, but they cannot prove this, despite recovering the first part of Maxwell's fictionalized autobiography.
