Summer 1910 on the coast of France. Several tourists have vanished. Inspectors Machin (Didier Després) and Malfoy Cyril Rigaux soon gather that the centre of these mysterious disappearances must be Slack Bay, where lives a very odd fishing family, the Bruforts and their eldest son, nicknamed Ma Loute (Brandon Lavieville). Every summer, the bourgeois Van Peteghems visit their villa by the sea in the same place and a peculiar love story starts between Ma Loute and the young and mischievous Billie van Peteghem (Raph). Confusion and puzzlement descends on both families, as events spiral to the bizarre and beyond.
Moderately amusing French film watching the over characterised ideal rich weekenders, and the over simple minded mussel fisher folk of the area in confrontation. It was flawed by being too long. Only two stars.
