Her summer job leads them straight into the Idyll of the Tyrolean mountains, where she was hired as a French teacher for the three siblings Leon and Melissa Landry during the school holidays. The three teens let Jeanette at first feel they do not agree with her strict father’s vacation plans, they can pursue their usual holiday pleasures but now indefinitely. To make matters worse, it allows even the resolute housekeeper her absent father’s sight. But the resistance of your students is not the only problem that afflicts Jeanette.
Ten years ago your parents before your own eyes cruel were killed, an experience from which she incorrectly has recovered during the long period in a psychiatric institution.

Meanwhile, strange things happen in the place and Jeanette feels persecuted not only by her recurring nightmares: the murderer of yesteryear seems back and has chosen as next victim Jeanette. But can she tell who?
