So they assume it must have drifted away, somewhere near the island, although Ben is dubious that the anchor could have failed to hold it in place.

Ben sets out to climb higher to see if the boat becomes visible, or there could be a route to another side of the island, but decides the mountains are too steep: at least crampons would be necessary.

They discover the ruins of an old cabin and some sort of commercial operation nearby, which they believe may have been a base for whaling.

Laura says they should build a fire to attract attention, but Ben takes off with the dinghy in an attempt to catch up with the boat.

Laura spends some time trying to make crampons from scrap metal that is lying around the area.

Eventually, she finds a research station, apparently built from shipping containers.

In early 2019, Vanessa Kirby and Jake Gyllenhaal were cast as the leads of the project, which was to be Bidegain's English language debut.

However, due to friction between the Bidegain (the director) and Gyllenhaal, the film was scrapped and retooled as a French production.
