A raid is about to take place in the southern French city of Aix. After a tip-off about a secret stash at her home, officers arrive at the house of a woman known simply La Vigne, and demand to search her premises. They know that she is a dealer and has most of her supplies stored in a system of underground cellars that connect several houses. And yet, before they can seize any of the illegal goods, she manages to throw all of the sacs currently at her home out of the window into the property of a neighbouring upper-class official, for whom the officers of course have no warrant. They have failed yet again and have to leave empty handed.
