This film is set in the future and space travel is much more commonplace. There are space stations and ships all throughout our solar system and there is a certain predictability about such travel. However, suddenly several ships disappear and are assumed lost. The space authorities on Earth are so concerned that they put a halt to all space travel until they can unravel this mystery--ships DON'T just disappear!
When most people think of sci-fi films, they usually don't think about East German. However, this nation produced several that were surprisingly good. Now you must understand, however, that this was NOT Hollywood. The budgets were not nearly as large and so the sets looked a little less sophisticated--but considering everything, they actually did a good job with the money they had. Quality-wise this film looks rather similar to ITV's "UFO" series from the same era.
As for the style film, I wasn't thrilled with how the plot bounced around so much--from the past to the present. It made the film a bit confusing at first. However, the plot itself was excellent--bringing up some wonderful points about just how far other intelligent life might be from our planet. Unlike most sci-fi movies where they go from one planetary system to another in what seems like minutes, this film realizes such a journey would really take several lifetimes. The utter loneliness and commitment to such a project was well captured here and the film really makes you think.
