A chorus teacher, Halla (Halldóra Geirharðsdóttir), is also Iceland’s most notorious eco-terrorist, and we follow her skulking around the countryside and taking out the country’s power lines, in protest of the government’s alignment with the foreign interests that are plundering Iceland’s natural resources. It’s a fun, funny movie whose two extended sequences of Halla in action are suspenseful and terrific—Jóhann Sigurðarson as her accomplice (and possible cousin) steals every scene he’s in—but the rest of the movie sags in comparison. (A subplot about Halla’s identical twin sister also feels like a reach.) But there’s a lot to like here, including the musicians and singers who appear onscreen, providing a live soundtrack and wry visual commentary.
