A tale of sexual encounters of one woman and several friends, family members and acquaintances, as seen (and told) from the perspective of a pair of satin blue panties.

In her small village in Vendée, Ludvine, an orphan, is in love with Jean-Pierre, but he is jealously guarded by her woman employer. On the day of the "Fair of Women", a traditional event where young men can choose the girl they fancy, Jean-Pierre picks out Ludvine.
