Later, Anna is celebrating New Year's Eve with family and friends and is congratulated on her being able to quickly develop a vaccine. She receives a call from the colonel telling her that they will leave shortly for the Kola borehole. Sounds of an unknown origin were recorded deep beneath the surface and shortly after 20 people went missing. The bore hole is not only as the public believes it, but also a deep underground research lab. Anna is tasked with retrieving samples.
