Track of the Cat (1954)

A family saga: In a stunning mountain valley ranch setting near Aspen, complex and dangerous family dynamics play out against the backdrop of the first big snowstorm of winter and an enormous panther with seemingly mythical qualities which is killing cattle. An arrogant, pitiless son (Robert Mitchum) and a rigid pharisaic mother side against a moral eldest son and and a defeated alcoholic father while the youngest son tries to lay low, hoping against hope to persuade his family to allow him to marry a girl he has brought to visit. The girl however draws venomous condemnation and the two elder brothers set out in the midst of a violent snowstorm on a dangerous mission to kill the deadly panther.
