Deep in the silent mountains wanders Amaya, a lost pup searching for her parents after a terrible snowstorm which, for the first time in her life, leaves her alone.
Until she meets a wise and aged wolf who, having saved her life, becomes her guide on an unforgettable adventure to follow the moon.
As they make their way through day and night across a wintery landscape, together they both learn profound lessons about love, sacrifice, life, loss and ultimately change.
