Duro Willoughby is a good enough fellow when in a normal state, but has brutal instincts when under the influence of liquor. He neglects his wife, and in order to save himself trouble, persuades a friend to spend some evenings with her. Things come to a climax one night when he loses his temper at cards in the club, and returns home in an especially coarse frame of mind. He is angry at his friend and his wife for not joining him in a drink, and his friend goes away in astonishment and disgust. His wife makes a pathetic appeal to him, and he strikes her. When she leaves the room he turns to the table and his glance falls upon a book entitled, "Because 1 Love You." In the fly leaf is written, "A token of love from Duro to Helen." He pens a note, telling his wife that he is going away and will not return until he has conquered the curse which has blighted their lives. After staying away for five years, he returns home. As he looks through the window he sees his friend talking to his wife, who has a baby girl on her lap. The passions he has held down burst forth. The friend comes out and Willoughby throttles him. He pushes away his wife, who brings the baby to him and begging him to listen a moment. She shows him a locket on the baby's neck. It contains his own portrait. The baby looks at the picture then at Willoughby, and murmurs, "Daddy." The veil falls from his eyes and he takes his wife and child in his arms.
