Jim Sherwood (Jack Holt), toughest logging boss in the timber country, takes on his toughest assignment when he agrees to cut an enormous volume of timber for Andrew MacKinley (J. Farrell MacDonald), who has to deliver the timber within sixty days. Jim, offered a big bonus, gets his men more pay and wins cooperation all around except from Harrigan (Willard Robertson), the job engineer. MacKinley is killed in an automobile crash, and his daughter, Kay (Grace Bradley, takes over. Sam Garvin (Charles C. Wilson), the general manager, wants Kay to sell out so his confederates can take over the contract. She declines and Harrigan flies to the camp. Jim, already sullen because he has just lost a huge quantity of timer in a dam break,is infuriated when Garvin says he has no intention of paying the promised bonus. Jim retaliates by slowing down production, and in order to run up expenses, orders Harrigan to build a section of railroad over a little-used gorge.
