Written by Mungiu, Fjord follows Mihai and Lisbet Gheorghiu, a Romanian engineer and Norwegian nurse played by Sebastian Stan and Renate Reinsve, respectively. Set in their modest ways, the couple tries to settle into their lives in Norway, having moved there after the death of Mihai’s parents to be closer to Lisbet’s family. Raising their five children with a conservative ethos, they don’t quite mesh with the liberal community that surrounds them. But their eager kids still build close friendships with the children of their progressive neighbors, Mats and Mia Halberg, a development that further underscores the two families’—and consequently, the two belief systems’—political and practical differences.

Tensions rise in town when the kids’ school raises child-abuse allegations against the Gheorghius after teachers notice some mysterious bruising on one of their kids. While the film never spells out their precise origins, Barnevernet steps in at once, separating their five kids (including a baby, still breastfeeding) from Mihai and Lisbet, placing them in foster care after the couple admits to some physical discipline that would be considered mild in Mihai’s culture, but is against the law in Norway. Claiming that they are being harshly discriminated against due to their religion and conservative beliefs,  the couple asks help from Mia, an attorney, to represent their case in the Norwegian court.
