A rollicking drama of satire, humour and suspense. Can you afford to miss it? Guy Lefevre is a successful landscape gardener. He and his wife Sibille drive through the winding heights of the Vosges Mountains but at the end of a long day, they have a blistering argument and Sibille gets out of the car, never to be seen again. What happened in those mountains? Arlette Van der Valk, Sibille's ex-neighbour, is suspicious and teams up with Henri Castang to prove foul play.
