A Hero of the Big Snows is a 1926 American silent adventure film directed by Herman C. Raymaker and written by Ewart Adamson.

The film also stars Alice Calhoun, Don Alvarado, Leo Willis and Mary Jane Milliken.

Nolan then brings Rin-Tin-Tin to the home of Mary Mallory, a woman he has unsuccessfully courted due to his wayward lifestyle.

As Mary endeavors to seek medical help for her sister amid a snowstorm, their dog sled overturns, leaving them stranded.

Responding to the distress call, Nolan rescues them, and the doctor reveals that the little sister's injuries were inflicted by a wolf, not Rin-Tin-Tin.
