Fjord centers a conservative religious family's clash with Norwegian authorities after their children report anti-LGBTQ teachings at school. A lesbian classmate faces denunciation, while neighbor Noora's emerging attraction to one of the daughters adds a subtle queer thread. These elements remain peripheral to the film's exploration of cultural tolerance and parental rights.

Fjord centers on a married Romanian-Norwegian couple raising five children under a strict Christian regimen of daily prayer, limited media access, and physical discipline. Their relocation to Lisbet’s Norwegian hometown triggers escalating clashes with neighbors and child-protection services that ultimately remove the children from the home.

The film affirms the evangelical Christian family's right to practice their faith without persecution, framing secular suspicion and legal scrutiny of their beliefs as unjust and positioning viewers to sympathize with their dignity and resilience.
