Life Is a Long Quiet River

Once upon a time, in a northern French town, there lived two families, from radically different backgrounds.
The Groseilles, who are poor, crass and shrewd people, live in council housing and subsist on welfare and scams. Among their six children, Maurice, 12, is undoubtedly the most cunning.
The Le Quesnoys, who live in an upscale neighbourhood, are as rich and well-meaning as they are devoutly Catholic. The father is the regional managing director of E.D.F., while his wife stays at home and cares for their five children. All is well, except for their daughter Bernadette, 12, whose behaviour seems a bit off lately.
Two worlds which were never supposed to meet.
Twelve years prior, on Christmas Eve, Josette, a young nurse, feeling downcast on account of the cowardly and scornful behaviour of Dr Mavial, OB-GYN, her married lover, had decided in a fit of anger and despair to switch two newborns: the Le Quesnoy's son and the Groseilles' daughter. Thus were born Maurice Groseille and Bernadette Le Quesnoy.
When Mrs Mavial dies and the doctor rejects any possibility of a future together, it is the last straw for Josette, who writes to both families, informing them of the swap and effectively wrecking her lover's career.
For some money, the Groseilles agree to send Maurice to live with the Le Quesnoys, pretending to their other children that they adopted him. Fearing for her mental well-being, the parents decide Bernadette will be kept unaware of the trade. The problem is that, after twelve years, nurture is definitely stronger than nature... and behind the clean-cut façade of the newly minted Maurice Le Quesnoy still lies the crafty mind of Maurice Groseille...

The initial box office success of the film was the result of a clever marketing strategy which included a trailer that did not have any footage or scenes from the film, and a poster that only had the title on it. In addition, the film didn't have any big names attached to it, except for veteran French actor Daniel Gelin. It was also the first feature film of Etienne Chatiliez who, before this, had had a successful career directing commercials that were known for their quirky and whimsical style. The film attracted 2.5 million moviegoers, largely due to the word-of-mouth marketing the film enjoyed.

Due in part to the film's being shown frequently on French television it has gained something of a cult following among young French people. The song "Jésus Reviens", sung during a scene set at a church, is instantly recognisable to many French youth as a key example of the film's many satirical digs at the French Catholic bourgeois culture in the era it was filmed.

The 2009 film Neuilly sa mère ! was heavily influenced by Life is a Long Quiet River.[2][3][4]

The film received 7 nominations at the César Awards :
