Toutes les filles sont folles

Céleste, a teacher in her early thirties, longs to meet her Prince Charming. Her older, rebellious sister, Rosalie, tells her that true love doesn't exist. After a minor accident, Céleste finds herself at the hospital.

She spots what she believes may be her ideal man lying on a stretcher and decides to kidnap him, with Rosalie as her involuntary partner-in-crime. But the two women kidnap the wrong man, having taken Raoul, an artist with an ordinary physique, who soon falls for Rosalie.

Meanwhile, when Céleste's crime is discovered, police chief Lorenzi and his nymphomaniac apprentice Vanille are assigned to the case.
