In 2069, the European Space Exploration Council’s (EUROSEC) Sun Probe discovers a planet orbiting the same path as Earth on the other side of the Sun. The probe’s findings have been transmitted to a power in the East by double agent Dr Hassler. Security Chief Mark Neuman traces the messages to Hassler’s laboratory and shoots him dead.
