For over 1,000 years, Icelandic law has made it illegal to import horses onto the island. For that reason, Icelandic horses are a pure breed, isolated by oceanic borders. During the summer months, the horses live a remote and wild existence, grazing in the highlands and raising their young. Every September, they are rounded up by local farmers and directed across the rugged terrain to reunite with their owners. It's a breathtaking tradition that unites the country. 'Herd In Iceland,' a film by Paul Taggart and Lindsay Blatt, documents the annual horse round-up. The result is a unique and moving portrait of Iceland's people, horses, and stunning landscape.
