Watch Law of the Timber

Henry Lorimen (Holmes) and his daughter Perry (Reynolds) run a lumber company, with a great new government contract. John Gordon (Brazeal) hires onto the company as a lumberjack. Soon a series of mysterious "accidents" plague the company, and Lorimen dies in a forest fire. Perry decides to take control of the company despite opposition from camp manager Barnes who's behind the sabatoge and finish the government job. Barnes plots to blow up a storehouse filled with dynamite and blame it on Gordon. However, Perry overhears his plan and tries to stop them, but Barnes knocks her unconscious and puts her in the cab of a runaway train. Gordon boards the train and starts a desperate race to get the train ahead of the explosion, before it kills them both.
