Alaska, Yukon Territory, 1899. In het afgelegen Yukon Territory wordt goud gevonden en een goudkoorts lijkt het logische gevolg. Een aantal bandieten onder leiding van Beauty Smith wil echter de hard werkende goudzoekers hun goud ontnemen. Zij hebben echter geen rekening gehouden met de wolfhond 'White Fang'.
Ja! de film Il ritorno di Zanna Bianca is nu beschikbaar om te kijken op Netflix in Nederland.
