The Little family employs trickery and disguise to rid their house of unwelcome newcomers, making a new friend in the process.

On a hill above the Big Valley, the Littles make a discovery that changes their world--tiny people are living in the forest up there!

When the Biggs go on a three-month vacation and an untidy family from the city moves into the house, the Littles must take action.

Aunt Lily Little has disappeared! The timing could not be worse as Mrs. Little is expecting a baby and desperately needs Aunt Lily. The family enlists the help of great big Hildy the cat and goes out into the snow on an adventurous search for the missing Little.

Meet the Littles, a family like any other--but with a few tiny differences! They live in the walls of the Bigg family house where they get everything they need, including food, furniture, and electricity. In return they make sure the house is always in good repair. But life as a Little means huge adventures. When you're only a few inches tall, even everyday things can bring big danger and excitement!
