Cattle baron Matt Devereaux raids a copper smelter that is polluting his water, then divides his property among his sons. Son Joe takes responsibility for the raid and gets three years in prison. Matt dies from a stroke partly caused by his rebellious sons and when Joe gets out he plans revenge.
CinemaScope western with a great cast
The film has what I believe to be the best film courtroom sequences ever, i.e. the cross-examination of Matt Deveraux.
Definitely worth seeing.
