The story of a woman who dreams to join an intervention group in the police department called RAID. Unfortunately, she is rather clumsy and both her family (and soon to be family-in-law) and a veteran of the RAID do not approve. However, Johanna is determined to prove them wrong.

Sibylle, a young Parisian with long teeth, intends to shine in her new job by buying a hardware store in the Basque Country to set up a supermarket. She imagines that she has "rolled" the old owner but the latter is under curatorship. Sibylle must therefore deal with Ramon, the nephew, to recover his money and sign as soon as possible. Otherwise, the ejection seat is assured. She will soon realize that the Basques do not intend to let themselves be made by a Parisian, however pretty she is.
