Plumber Freddie Blacklock lives with his wife Thora in the north of England. Freddie is a down-to-earth bloke who likes to take things easy whereas Thora has ambitions for the couple to improve their social standing.

The Blacklocks have been married for 25 years, their children have flown the nest and they know each other inside out. But, as the adage says, familiarity breeds contempt... or at least a major headache.
