In a remote Icelandic farming valley, two brothers who haven't spoken in 40 years have to come together in order to save what's dearest to them - their sheep.

Winner of the Un Certain Regard prize at this year's Cannes festival, Grímur Hákonarson’s stunningly shot drama focuses on two Icelandic sheep farmers whose decades-long feud comes to a head when disaster strikes their flocks.
