Millionaire meat packer Peter Cameron, greedy for more money and power, maneuvers an alliance between his daughter Rose and George Gray, the son of Cameron's business rival Max Gray, in order to increase his control of the food industry. George, a lawyer, opposes the trust, and as a result is professionally ruined by Cameron, disinherited by his father, and jilted by his fiancée. Out on his own, George gets a job at a mill and starts at the bottom. When an epidemic breaks out among his fellow laborers due to their eating spoiled meat from the trust, George secures evidence of criminal practices which ultimately brings about the conviction of Cameron and the trust. In championing the rights of the downtrodden, George wins back Rose and reforms Cameron.
