Half the film involves trees falling down and the same stock footage of the lumber industry. There are two warring camps. One is sending men to shoot the workers in the other camp. It is getting ugly. There are so many injuries that the foreman (a sort of Nelson Eddy kind of guy) gets in touch with the owner (who happens to be a rich flapper, engaged to a surgeon). She goes to the camp with her fiancé. He will do the doctoring while she assesses the situation. There is no reason for her to be there other than to advance the plot and get her to fall in love with the handsome foreman. At some point, the guy (who acts before thinking) finds that the opposing camp is about to dam up the river and ruin their business. After a confrontation with a couple of lumberjacks, he is knocked unconscious and thrown in a ravine. He is later found by the surgeon who is put in a position of using wolf blood to save his life. Of course, he now begins to act wolf-like. Some say this was the first werewolf movie. There are some fun moments, but, over all, it is just quite moronic.
