The state government plans to build a flood-control dam and condemns the property of the local farmers and ranchers, including The Three Mesquiteers. The state intends to compensate the land-owners fairly, but a crooked real-estate promoter complicates things. The ranchers, led by Stony Brooke ('John Wayne' (q)), Tucson Smith ('Ray Corrigan') and Rusty Joslin (Raymond Hatton) fight back against both the law and the crooks.
