A group of students go the location of the infamous Dyatlov pass incident to make a documentary, but things take a turn for the worse as the secret of what happened there is revealed.
One of the characters mentions he's using a Suunto compass. Suunto is a well-known Finnish manufacturer of compasses.
Although Holly's camera went back in time with her, there was another one containing exactly the same footage inside the hatch. This is the same camera, retrieved by soldiers during the Dyatlov Pass incident in 1959 and brought inside.
Several names and words in the final credits start out with some or all of the letters being spelled with Cyrillic script (used in the Russian language). They gradually morph into English.
