Grey.

In a snowy forest in medieval Germany, Börn and his horse Gunnar come across a slain mother wolf and her frightened pup, Grey. Börn adopts the pup and raises Grey as a companion. A few years later, Börn, Grey and Gunnar enjoy a summer day together in the forest, when a wild wolf pack attacks the trio, endangering them all. As Börn prepares his bow and arrow to fight, Grey recalls the death of his mother and the arrow that killed her. Grey must make a decision: stand by his human friend, or take to the wild with those of his kind.
