In 1970, debris from the 1908 Tunguska meteor is found. It turns out to be recordings from a spaceship that crashed. The ship's origin is determined to be Venus, and an international team sets out with their spaceship Kosmokrator. The 'Silent Planet' doesn't respond to contact attempts. While the Kosmokrator is in flight, the record is decoded and it turns out that the Venusians seemingly planned to invade Earth in 1908. Should the Kosmokrator still attempt to get in touch with the aliens? And why are they silent now?
