Ed Newton, a young engineer, encounters many difficulties in the construction of the new dam. Bill Dolan, one of the wealthiest cattle men in the district, is especially against the building of the dam and does all in his power to prevent the engineer from completing it. Dolan's daughter meets Newton and they fall in love with each other. Later the surveying is completed and the dam is built. The cattlemen attack the engineer and his party but find that violence is to no avail. Ed and his sweetheart go over the dam and one of the cattlemen, who is in love with the girl, attack the engineer in the tower. There a struggle ensues and Newton finally grasps his assailant around the waist and hurls him over the railing. Turning to the girl he clasps her in his arms. - Moving Picture World, November 25, 1916
