It’s a mystery why exactly John (Paul Higgins) and Karen (Kate Dickie) have renounced civilization in order to live like feral creatures in a dirt cave in the woods. John hunts rabbits with his bare hands, and when such riches are unavailable, the pair sustain themselves on insects.
But when a poisonous spider bites Karen, John breaks their self-imposed isolation to get help. This leads him to befriend local farmer Andre (Jérôme Kircher), who becomes suspiciously over-invested in the pair’s wellbeing. As the couple’s backstory unfolds, an impending sense of doom casts a pall over their small world. The seeming serenity of the forest is revealed to be as fragile and unstable as the characters, who, it becomes apparent, are on the brink of rupturing with violent emotion.
