When asked to sum up the entire series in a few sentences, producer Eric Laroche said: "After a complex mooring manoeuvre at the ISS, ground control lost contact with the station and the crew is in distress. At the same time, a decapitated and wax-covered body is found on a roof in Kazakhstan. The identification leaves no room for doubt: the body belongs to Anthony Kurz, an American astronaut who is currently in the ISS, in orbit 400 km away, in space. The French astronaut, a French astronaut, who had been dismissed from the space program, was convinced that Kurz called her for help from the ISS. She is teaming up with Isaak Turgun, a Kazakh policeman disavowed by his superiors, to resolve this mysterious paradox: Could Kurz be living in space and dead on Earth?"
