Two girls, left to themselves for a weekend unintentionally reach a telephone network of sexual encounters. They mingle with calls to make an appointment at their home. Males are rushing in... and even a woman. They experience everything, from the most disturbing to the most perverse as their parents have the good sense to extend their absence. They ultimately decide to "try" all members of the network. This sulfuric film on liberalism of the time drew a record number of spectators during its release on April 4, 1979 in the ALPHA-FRANCE movie theaters.
