Andrew and Maggie Prentice have taken early retirement and plan to move to France, however when tragedy strikes they are left to care for their three grandchildren: Georgia, Jake and Michael and are going nowhere fast.
Maggie has the flu and is therefore confined to bed, so Andrew is delegated the main housekeeper role. However the grandchildren aren't best please with Andrew's reign.
After embarrassing their grandchildren in public, Maggie and Andrew receive a stern lecture on acceptable public behaviour. This triggers a rebellious reaction from the pair, as they decide to up the ante by behaving even more embarrassingly than they had previously - much to their grandchildren's dismay.
Maggie feels superfluous as the children have been turning to Andrew for support with their problems, so she decides to leave home.
Maggie becomes a cub mistress and Andrew has a reunion with his former secretary. Meanwhile their friend Rosie tries to fix a raffle so that the family will win a car.
The Prentice family take a holiday aboard a narrow boat, but all soon goes awry when the 'crew' begin plotting a mutiny.
Georgia announces that she'll be fasting for world peace, but Maggie begins to worry when she doesn't start to eat again. Meanwhile Jake demands he be bought deodorants and Philip falls in love with a ballerina.
Maggie discovers that her neighbours are moving because her household is too noisy. Philip is unhappy at the prospect of Andrew and Maggie performing a jive at his school dance.
Maggie finds out that Philip has been shoplifting from the local mini market, but he is also being bullied by a boy at school. They decide to pay the boy's parents a visit.
