In 1965, going into outer space, Alexei Leonov witnessed the disaster - an unknown spacecraft, later called "Object 1", crashed near the moon. Thus began the competition of the leading powers of the Earth for who will receive more alien technology, better adapt them, faster find the owners of the ship and come into contact with them. A hundred years people are exploring the solar system, reach speeds of 200-250 km/s, but beyond the system do not go. It is not possible to detect any more traces of aliens .. In 2089, an astrophysicist from the OSR (United Socialist Republics, restructured USSR) proposes a completely new theory of the structure of the universe, which opens the way for humanity to deep space and at the same time explains the collapse of Object 1. In 2091, the OSR sends the Vestnik, a ship equipped with a hyperon-magnetic engine, to SGR 1806-20, in the constellation Sagittarius. It is there that scientists need to look for traces of mysterious guests of the solar system.
