Cold front

A long-lost couple - Sasha, a girl from a wealthy family, and her boyfriend Ilya - spend the winter holidays in a cut off from the outside world house on the ocean in northern France. On New Year’s Eve there are two seemingly unrelated events: near the hero’s house, the surf throws ashore the carcass of an unknown animal, and the same evening Ilya meets in the vicinity of Masha – a Russian girl who allegedly accidentally got off the train at the wrong station and who has nowhere to sleep. Something is clearly wrong with Masha, but Ilya and Sasha, keen on clarifying the relationship, at first do not notice sinister oddities in the behavior of an uninvited guest.
