[1] Lee Preston, aka Leland Bruce (Lowery), kills a man in self-defense but flees to the redwood country when the law makes it a murder charge.
There he meets Lynn O'Malley (Gilbert), the niece of "Sandy" McTavish (Farnum) who runs the trading post.
Lee learns why this is good trapping country as the timber barons across the lake are ruthlessly cutting the trees and driving the animals across the river.
The trappers appeal to him to take a petition to the Governor which would prohibit the timber people from coming to their side of the lake.
