 Jeanne and Mimi look down on some punk kids in the street they presume to be responsible for the recent series of thefts, but actually Mimi s  sweet, well-bread  small niece Julie is the one who loves coming to the sweet shop because the little minx  helps herself  while the pair is wagging their tongues; Odilon is recruited as shop detective. When Mimi tells her about a reception in city hall for all civil servants, with a minister, she is determined to go, even though she can t find a hairdresser in time, but Lus claims that s up her alley- well, if you like punker colors. Jeff looks for excuses not to go, because absentees get half a day off work. Meanwhile dumb Hugo was tricked by Gentil to vacate the bathroom for a fake phone call two days in a row, and takes the girls  advice to start copying Gentil, exterior and grumpiness; Gentil ends up retorting.
