Georges (Mathieu Almaric) is a renowned speleologist who is called to either a south or central American location, after a group of vast sinkholes/chasms have been discovered in a forest. Accompanying him is his wife France (Nathalie Boutefeu), who has to live in an isolated inn while her husband is exploring.
Alone, with very few people to talk to, France starts hearing things, which she starts associating with the sinkholes her husband is exploring. Other stranger things still begin happening which leads France to wonder if the chasms are as far away as would appear. or maybe they're just getting nearer to her. Or maybe they somehow wish to communicate...
The phrase "interesting premise, terrible execution" immediately leaped to mind for me when watching this as it's quite frankly terrible and amazingly for a film of 62 minutes in length, it feels like a three hour affair, with it being perfectly at home with long lingering shots and exposition and weird ambiguous stupid stuff that doesn't make a lick of sense.
Those that like art-house or fantastical cinema may find much to like here but I was personally bored to tears by it and found it pretty nonsensical. Nicely shot though but precious little else going for it, with nothing really adding up satisfactorily for me. Didn't particularly go down well at the Dead by Dawn Festival either where I caught it. 3/10 a film to be avoided.
