When their father is deployed in the WWII Navy, he directs the five Mitchell children to look after their mother-- and not to turn the house into a zoo, adopting animals-- ESPECIALLY not a dog. Well, somehow pets keep finding them... but what will happen when their father gets back? Also, what will happen to refugee Una, living down the street with the nasty Hugh and his complaisant Mother? The Mitchells have a number of class 1940s family story style adventures.
