Bender and his friend, the Widow Templeton, decide that bachelor life does not agree with Jenkins, consequently they search for a wife. When Jenkins sees the widow, however, all thoughts of any other flee, and he immediately proceeds to win her. Angered by this, Bender resolves to "get even," and presents the newly-married couple with a bottle of water, telling them that it will change color in the event of either one digressing from the path of fidelity. While traveling, Jenkins is attracted to a flashy young lady on the train. As they pass through a dark tunnel, he kisses her. Meanwhile, Bender has persuaded the wife to accompany him to dinner. He bores her with his advances. Later Bender pours ink in the clear water of the magic bottle, which is discovered first by Jenkins, who is panic-stricken. He tries to conceal the supposed symbol of his perfidy, but is interrupted and places the bottle back in the cupboard. His wife finds the blackened water next and also wants to conceal it. There is no place to pour the water save in Bender's high hat. Then she refills the bottle with clear water. Bender lingers to see the result of his plot and is surprised that things turn out all right. He puts on his hat to leave, and the inky water drenches him.
