This a French TV serial (with subtitles), set in the near future, about the first manned missions to Mars. Ulysses, a European space craft funded by William Meyer, a fabulously rich Swiss entrepreneur, is arriving in Mars orbit when they learn that they have already been beaten to the planet by a much faster American craft, funded by an equally wealthy US businessman, Ivan Goldstein. It becomes evident that the US craft experienced major problems on landing, so the European crew decide to attempt a rescue. They manage to land nearby (not without their own problems) and find one survivor in a spacesuit, but he has a surprise for them. After this, the plot evolves from a routine "trip to Mars" to something of much greater significance.
The serial ran for ten episodes of 25 minutes each (on BBC4 in the UK) and is structured in such a way that it isn’t possible to say any more about the plot without spoilers. I will just say that I was reminded of the film 2001, not so much in the specifics of the plot as in the atmosphere of a cosmic mystery gradually unfolding. It is intriguing and well worth seeking out.
