Ed Newton gets into trouble with the ranchmen as soon as he starts surveying for a big dam. Tom Daniels rides up and informs him that Bill Dolan, one of the wealthiest ranchmen, wishes to see him. He goes and is told by Dolan that the work must be stopped at once. Dolan tries to impress upon Newton, but without effect, the fact that his reservoir meets all the requirements. Here, Newton meets Margaret, the ranchman's daughter. After the surveying has been completed and the work begun, the arrogant ranchmen attack the workers of the dam, in which battle Ed Newton and Bill Dolan are seriously injured. Hostilities having ended, the injured engineer is cared for at the Dolan home. During his stay there, he and Margaret have fallen in love, much to the disgust of Tom Daniels, who thought that he would be the one to win her hand. So Daniels swears revenge. When the big dam is finished, Ed shows Margaret over the place. In the tower, they discover a bomb, which had been placed there by Daniels. Margaret throws it into the river. A fierce struggle ensues between Daniels and Newton, in which Daniels is finally bested and thrown into the river below. -Moving Picture World, November 4, 1911, p. 416, 418.
