Misunderstanding French ways lands Hester in a French jail. Misjudging the local speed limit as he drives to her aid gets William arrested, too. Hester's only hope is Emma's husband, who has been taking night courses on French law.
Hester agrees to show a group of British house-hunters some local properties, while William struggles with a plumbing problem at his own house. William's difficulties mount when Hester's tour party shows up to use the bathroom.
Emma's in-laws arrive unexpectedly for a visit, and the Fields look for any excuse to get out of town. They go on a camping trip and somehow end up in Paris. Once there, William and Hester realize they shouldn't have bothered.
Hester runs afoul of the mayor when she tries to discipline his daughter, while William has problems with his own daughter Emma. Hester tries to explain the concept of fair play by explaining the rules of cricket.
William learns that getting fired in French sounds just the same as it does in English. The Fields know they can always go back to England if the worst comes to the worst. When they learn who's renting the farmhouse next door, it soon does.
