"Tom" (Andreas Pietschmann), wife "Julia" (Émilie Duquenne) and their two teenage kids are having a peaceful boating holiday when huge meteor-sized things start falling from the skies. Next thing - well where has the ocean gone? Their boat is now perched on what we assume is the sea bed, an arid desert like landscape, and the family are suitably perplexed. What now? Well they do manage to make contact with a nearby diver whose bell was stranded on the sea bed, and he tells them some stuff about the poles being reversed and the water all skedaddling to the far side of the Earth. Maybe go join up with him? Well before that can happen they encounter another survivor, but he's a nasty piece of work and soon the family are reduced in number and having to make their way on foot to find their radio contact before they are crab food. Yep, it's terrible. It's not that it's just entirely implausible from start to finish, it's that the acting is as bad as I've seen in ages and the fact that it is in French ought not to put you off unduly because there is precisely nothing at all in the dialogue that enhances either the film in general or any sense of peril that's distinctly absent throughout the entire ninety minutes. What was most worrying was that it ends as if there might be a sequel. As my annual Paramount+ subscription comes to an end, I really am wondering whether this really is the best they can do from a century of film-making.
