When a mother goes to work in a factory during World War II, Porky Pig is hired to baby-sit. He quickly finds out that the baby is a violent-tempered infant. He tries to use a child psychology book to control the baby, to no avail, including a scene where the baby does a Winston Churchill impression. Eventually, the mother returns and uses the book to discipline the baby—by spanking.
