In 1961, United Nations secretary-general Dag Hammarskjöld’s plane mysteriously crashed, killing Hammarskjöld and most of the crew. With the case still unsolved 50-plus years later, Danish journalist, filmmaker, and provocateur Mads Brügger (The Red Chapel, The Ambassador) leads us down an investigative rabbit hole to unearth the truth. Scores of false starts, dead ends, and elusive interviews later, Brügger and his sidekick, Swedish Göran Björkdahl, begin to sniff out something more monumental than anything they’d initially imagined. In his signature agitprop style, Brügger becomes both filmmaker and subject, challenging the very nature of truth by “performing” the role of truth seeker. As Brügger uncovers a critical secret that could send shockwaves around the world, we realize that sometimes absurdity and irony are the emboldening ingredients needed to confront what’s truly sinister.
