[3] Agnès Le Roux, a young independent woman, returns to Nice in 1976 to have a new start in her life after a failed marriage.

Her mother, Renée Le Roux, a wealthy widow, is fighting with other shareholders for control of the Palais de la Méditerranée, a casino on the French Rivera.

The casino is facing difficulties and in one night, it loses five million francs to professional gamblers who very likely tampered a game.

Agnès, determined to make it on her own, opens a small bookstore where she sells African artifacts and Asian textiles.

Renée, with the help of her lawyer and personal adviser, Maurice Agnelet, and her daughter's decisive vote on her favor, takes control of the Palais de la Méditerranée.

[15] Nicolas Rapold writing for The New York Times commented that "Mr. Téchiné ’s methodical storytelling covers more narrative ground than the drama requires, sapping the film’s energy."

In his review for the San Francisco Chronicle, Mick LaSalle described In the Name of my daughter as "Lacking action to the point of seeming immobile, Mr. Téchiné nevertheless amasses a catalogue of anger, desire and sex, enhanced by stunning landscapes of villas and a parade of the rich and glamorous haut monde at play.
