A beleaguered mother attempts to ensure that everything is perfect for her daughter's wedding despite the fact that their dysfunctional family is coming apart at the seams in writer/director François Dupeyron's darkly comic family drama. Christie Mousse is about to get married, and what she doesn't know is that her deadbeat dad recently gambled away the money that was intended to pay for the reception. As Christie's long-suffering mother Sonia dutifully reassures her daughter that the ceremony will go off without a hitch, the lawless exploits of her angry adolescent son Victor gradually threaten to cast a shadow over her daughter's picture perfect wedding. Recently, Sonia has been saving up money in hopes of purchasing the Laundromat where she currently works, though before the day is through she will be forced to contend with a development that threatens the livelihood of her entire family. Will Sonia manage to keep her cool as usual, or will this be the day when she finally tells everyone what's really on her mind?
