Desert Blossoms (1921)

Steve Brent, a construction engineer with an excellent reputation, is blamed for having used inferior materials on a bridge that collapses. Bert Thornton, his employer's son, is actually responsible, but not wishing to expose him, Brent surrenders his position. Assuming another name, he goes west to work on a desert irrigation project where the manager's daughter, Mary Ralston, recognizes him but keeps his secret. Ralston is informed by an enemy of Steve's, but Mary helps to protect Steve's name until he is exonerated and becomes free to marry her.
