Catherine is scouted by magazine editor Judith and her co-worker/boyfriend Michel. Promoted under the stage name 'Chouchou', Catherine becomes a big asset but things become complicated when she and Michel start developing mutual romantic feelings. These are exacerbated when Judith gets the idea of doing a wedding-themed shoot, wherein Catherine plays the part of the blushing bride and Michel finds himself as the groom.
