In a remote Icelandic valley, brothers Gummi and Kiddi coexist as sheep farmers, renowned for their exceptional, ancient lineage of rams. Despite living in close proximity, a bitter silence has stretched over four decades. When a deadly disease strikes Kiddi's flock, the threat looms over the entire valley, prompting authorities to order the culling of all sheep. Unwilling to accept this fate, Gummi and Kiddi each devise their own strategies to combat the looming disaster—Kiddi resorts to his rifle, while Gummi relies on his cleverness, setting the stage for a clash of wills.
