Gunner Peterson is a veteran dynamite man working for Jake and is romantically interested in Jake’s daughter Mary. Johnny Brown, son of Nellie Brown who operates a boarding house, finds college too tame after his stint with a demolition squad in the army, and decides to quit. Getting a job with Jake, he is soon resented by Gunner when he tries to introduce some new methods and also starts showing an interest in Mary. A truck loaded with dynamite gets away from Hard Rock Mason and the loss of the truck causes Jake to have to borrow money from Nellie to keep his business going.
