Mrs Hardy is annoyed that her husband Oliver seems to spend more time with his friend Stanley than with her. After a furious argument, Mrs Hardy says that she is through if Ollie goes out with Stan again. Stan suggests that Ollie adopts a baby, which he does. Unfortunately, his wife has left their apartment on returning, and a process server delivers a paper informing Ollie that she is suing him for divorce, naming Stan as correspondent. The boys are now left to look after the infant on their own.
