Le Maire follows Harriet, a potential candidate for the role of Mayor of Rachelais; the small French village that she and her husband Roy have settled in. Their perfect little French life, away from the issues occurring in the UK, seems full of peace and 'tranquillité'. However, on the eve of the vote, her irresponsible and unpredictable brother Ed comes crashing into their continental lives (as well as the local vineyard), putting all of her plans into question.
