Jacqueline falls under the spell of Philippe, who has come to her home to sell her a vacuum cleaner. She welcomes him into her home and gives him a boost. An early-retired prostitute, she owns a small sex shop which, until now, had been poorly run by her ex-husband Jean. To keep Philippe close to her, she entrusts him with its management.

The story of three characters who lead their lives as if they were running a store, day by day. Three inseparable characters who would not exist if they had not met each other, who make life impossible for themselves and turn their daily lives into a series of improbable numbers.
