live-action TV series, which also re-used many of the film's props. Plot In 2069, the European Space Exploration Council's (EUROSEC) Sun Probe discovers a planet on the same orbital path as Earth on the far side of the Sun. The findings are transmitted to a power in the East by double agent Dr Hassler. Tracing the messages to Hassler's laboratory, Security Chief Mark Neuman corners the scientist and kills him. EUROSEC director Jason Webb convinces NASA representative David Poulson that the West must send a crewed mission to the planet before Hassler's allies in the East. NASA astronaut Colonel Glenn Ross and EUROSEC astrophysicist Dr John Kane are assigned to the mission. After undergoing training at the EUROSEC Space Centre in Portugal, Ross and Kane blast off in the spacecraft Phoenix. They go into an artificial hibernation for the outbound journey, with "Heart-Lung-Kidney" machines maintaining their vital functions. Three weeks later, Phoenix reaches the planet and Ross and Kane are revived. Scans for life prove inconclusive, so the astronauts decide to make a surface landing in their auxiliary craft, Dove. During its descent, Dove is damaged in a thunderstorm and crashes in a mountain range, seriously injuring Kane. The astronauts are picked up by a human rescue team, who tell Ross they have landed near Ulaanbaatar, Mongolia. It appears that Ross and Kane have returned to Earth, and they are flown back to the Space Centre. Neuman and EUROSEC official Lise Hartman question Ross, who denies that he aborted the mission. Later, Kane dies of his injuries. Ross discovers that people are now driving on the wrong side of the road and that he can no longer read printed text because it is all backwards. He comes to the realisation that he is indeed on the unknown planet, a Counter-Earth where every detail is a mirror image of his Earth. Ross's wife Sharon refuses to accept his claims, but Webb is convinced when Ross demonstrates his ease in reading reflected text and Kane's post mortem examination reveals that his internal organs are on the "wrong" side of his body. Ross theorises that the two Earths are parallel and that his counterpart from this world is experiencing similar events on his Earth. Webb proposes that Ross retrieve the flight recorder from the orbiting Phoenix and return home. EUROSEC builds a new Dove designed to be compatible with the reversed technologies of
