The devil's grandmother sends her grandson to visit the Punch and Judy family. The devil hypocritically promises to behave in an exemplary manner, but does the opposite. He secretly eats the pudding, smashes the bowl, lies through his teeth and flees when he is caught by the policeman. Punch and the policeman pursue him and catch him with great difficulty. The adventure ends with a clear defeat for the devil and the devil's grandmother's anger at her clumsy grandson, who has once again been caught out.
