Plot

John Dowling, a greedy factory owner, cuts his employees' pay while raising their food prices at the company store. The employees strike but to no avail. Mary Garvin visits Dowling to plead the laborers' cause, but because her mother had once refused his marriage proposal, he attacks Mary out of revenge. In the struggle, Dowling is shot, and Mary is tried and convicted of murder. Before the execution, foreman "Bull" Thompson boasts that his bullet killed Dowling during Mary and the factory owner's struggle, and Dowling's son Chester, who has attempted to introduce reforms into the factory, races to the governor's train to secure a pardon for Mary. After Mary's release, she and Chester are married.

John Dowling is the boss of Millvale, a grasping, greedy profiteer, who underpays his employees and overcharges them for their food. At last the goaded slaves strike and Dowling jeers. They attack his home and he shoots down a "trespasser," backed by the law. When Mary comes to remonstrate, he attacks her and during the struggle he is shot. In spite of all pleas Mary is condemned to suffer death punishment, but at the last moment the truth comes to light and Mary is saved after a tremendous automobile chase.—Moving Picture World synopsis
