Oulage has everything arranged for New Year's Eve, when he will finally kiss Brigitte, the girl he adores, at the stroke of midnight. Brigitte is throwing a costume party, so that'll be the time. Oulage has everything planned, but Brigitte has invited a gang of parasitical friends: an old girl friend who never leaves Brigitte's side, a manic-depressive police officer, a paranoid psychopath, a cannabis-addict suffering withdrawal pains, a stunning Cuban woman on the prowl for immigration papers, and others who do everything to ruin Oulage's life.
