Sinopsis de la película

In the summer of 2003, a group of shepherds took a herd of sheep one final time through the Beartooth Mountains of Montana, in the extreme north-west of the United States. It was a journey of almost three hundred kilometres through expansive green valleys, by fields of snow, and across hazardous, narrow ridges - a journey brimming with challenges. The aging shepherds do their very best to keep the hundreds of sheep together; the panoramic high mountains are teeming with hungry wolves and grizzly bears.
