The game Adventure Secret Files: Tunguska begins with a frustrating kidnapping.

Nina Kalenkov's world is turned upside down when she learns that her father, scientist Vladimir Kalenkov, has disappeared without a trace.

As the police cannot (or do not want to) help, Nina decides to search for clues about her father's fate.

Along the way, she meets Max Gruber, one of her father's colleagues, who spontaneously offers his assistance.

The search leads Nina and Max to a mysterious disaster in the Tunguska region of Siberia in 1908, which Vladimir Kalenkov had investigated.

The quest for an answer takes the two Berlin heroes across the globe and to Antarctica, and it soon becomes clear that there are others interested in Nina's father's secrets.

It appears that there is much more to the kidnapping of an elderly man.
