A novel by Arthur Stringer was the source for this two-fisted Universal programmer. When a giant utility company begins building a dam in the Northwoods, feisty conservationist Heather McHale (Irene Hervey) battles tooth and nail to keep the land sacred. Impressed by her determination and grit, construction engineer Owen Merrill (Kent Taylor) falls in love with Heather. He's even willing to battle local bully-boy Doug McKenzie (William Lundigan) to defend the girl's honor, which is certainly worth defending. In a climax that may or may not meet with the approval of the EPA, Heather allows the project to go through when it's discovered that the dam will help preserve the local salmon population.
