The chronicle of a great love, which has its roots in the most authentic traditions of the Aosta Valley area. On a snowy and cold winter night a young novice veterinarian has to fight against the unexpected adversity of life to prove to herself and to a gruff and old mountain farmer of that she can carry out a special mission: assist his beloved Bufera, cow queen of the herd, to give birth to a calf. It’s a matter of life or death.
