Anne Shirley is all grown up and married to her longtime sweetheart Gilbert Blythe. What's more they have six wonderfully mischievous children - who've just discovered a new secret hideout. When the Blythe boys and girls learn that an eccentric family has moved into a nearby mansion, they are bubbling over with curiosity. The new family is the Merediths, and they have two boys and two girls of their own. They also shelter a runaway named Mary Vance, but sadly she's about to be sent away to an orphanage. Can the Blythe children find a way to help?
