It was released on 22 May 2018 to critical acclaim and selected as the Icelandic entry for the Best Foreign Language Film at the 91st Academy Awards ceremony, but it was not nominated.

[3][4][5] Halla, a choir conductor and eco-activist, plans to disrupt the operations of a Rio Tinto aluminium plant in the Icelandic highlands, purposely damaging electricity pylons and wires to cut their power supply.

The band is played by Magnús Trygvason Eliassen (drummer), Omar Gudjonsson (sousaphonist) and Davíð Þór Jónsson (accordion & pianist).

[14] Peter Bradshaw, for The Guardian, praised Halldóra Geirharðsdóttir's "attractive and sympathetic performance" as Halla, and called it a "well-turned, well-tuned" film that was "confidently and rather stylishly made".

[6] Jay Weissberg, for Variety, called the film "a delightful follow-up to Of Horses and Men", and praised the director for "arranging beautifully shot picaresque episodes around a central figure who lives the ideals of the heroes, she has hanging on her wall, Mahatma Gandhi and Nelson Mandela".
