Gummi kills his flock before the biohazards team arrive, but hides a few ewes and a ram in his basement, as they are the last of their breed.

When a member of the cleanup team also discovers the sheep, the two brothers are forced to collaborate and attempt to drive them into the highlands in a blizzard.

Rams was based on a story told by the director's father about two brothers sharing the same land who had a falling out over a woman and stopped speaking to each other for 40 years.

"[13] The film was shot on locations in the Bárðardalur valley in north east Iceland between Akureyri and Mývatn.

Sigurður Sigurjónsson and Theodór Júlíusson, two of Iceland's best-known actors,[15] prepared for their roles by working on a sheep farm.

The critical consensus states: "Rams transcends its remote location—and somewhat esoteric storyline—by using the easily relatable dynamic between two stubborn brothers to speak universal truths.

"[16] On Metacritic, the film has a weighted average score of 82 out of 100, based on 24 critics, indicating "universal acclaim".
