Neal hates to give up his evenings with the boys, even for his wife, Betty. She gets a burglar scare and insists on his staying home. However, he wants to go to a mask ball, so he gives her a powder, telling her it will make her sleep soundly. She slips the powder into his favorite decanter, hides his costume, and then retires. In the kitchen, the cook gives a policeman some of the doped whiskey. Neal takes the cop's coat, hat and stick and starts for the ball. On the way he is called on to restrain a wife-beating husband. He gets a black eye, so decides to go home. Meanwhile the cook has tried to waken the real policeman. A burglar enters, drinks from the decanter, and rolls under the table, asleep. The officer wakes up, upsetting his chair, so that Betty is awakened. Taking a gun, she looks for the trouble, and shoots at the officer in the kitchen, which awakens the burglar. Running into the dining room, Betty tries to capture the burglar, but he is getting the best of her, when Neal rescues her. The officer makes the arrest, while Neal promises to stray no more.
