Upon her father's death, Esther Regan promises to carry out his wishes that she protect his workers and manage the Regan Steel Mills as well as he. The Associated Trust has been trying to gain control of the Regan plant, but has always met with resistance from Regan. Now that he is dead, they see their opportunity for a coup and send Darwin McAllister to accomplish the deed. However, McAllister is impressed with the way the plant is run and, growing fond of Esther, resigns his position to help her fight the trust. This arouses the ire of trust president Cyrus Moulton, who employs Dan Cullen to sabotage plant operations by delaying the shipment of a critical contract. McAllister and Esther appeal to the workers; united, they manage to rout the trust and get through to deliver their shipment.—AFI
