Woman at War (2018) on Netflix

Plot summary

Halla is an independent woman of fifty who conducts a choir in Iceland. Unknown to those around her, she is the environmental activist called the Woman of the Mountain, who damages pylons and power lines to cut the power supply of the aluminum plant under construction in the highlands. Her actions grow bolder, the talks between the Icelandic government and the corporation behind the smelter stall, and the state answers with more police and a campaign to discredit her. Then a long-forgotten application to adopt a child from Ukraine is approved, and a girl waits for her there. Halla has to weigh the fight she has taken on against the adoption. A three-man band and a trio of Ukrainian singers play on screen beside the characters.
