A teacher, driven to exasperation from insults and insubordination, takes her class hostage.

Annecy. When Valentin Poncet, an exemplary firefighter with a remarkable past, is found dead in suspicious circumstances, Commissioner Cassandre and her team must untangle the threads of a murder that appears to be linked to a burglary. Between the discovery of a mysterious fiancée Val may have had, the shadow of a dangerous arsonist looming overhead, and tensions within the fire station—still reeling from this second recent tragedy—each clue raises new questions and sheds light on a tragic family history with deeply buried secrets.

Spring reveals the secrets buried under the Sapenay pass, overlooking Lake Annecy. As the snow melts, a hiker discovers in a cave the body of a woman, killed by a bullet through the heart. Near this still anonymous victim, two other bodies, men, lie under the snow, frozen for years.

Everyone's in shock when esteemed doctor Pierre is found to have killed his wife. 15 years later, released on parole and determined to find the culprit, he is rejected by his sons and only finds support with his daughter, Nina.
