Scientist Nicholas Sinclair is part of a scientific team sending robot probes through time for research purposes. One is sent back to an apparently barren desert in 1973, only for a family to get lost and stray into the robots landing area. Fearful that the probe will kill the family, Sinclair attempts to destroy the robot, but to no avail. He then decides to travel back in time to save the family. When he returns back to his present, he discovers that he has altered the course of history, and the world he has returned to is a very different one to the one that he left. Sinclair must now attempt to return to the lab(set amongst ruins in this new world) to reprogramme the original experiment
This film is a bit of a paradox in itself. Whilst in the original world it carries its themes off with considerable style, and continues to do so when Sinclair travels back to 1973. Where it really comes unstuck is when Sinclair comes back to his present, only to find that his world has changed. Then it sadly becomes just a routine shoot em up with lots of big explosions and macho posturing. What a shame, as with such a strong beginning the film promised so much more.
Still, the film is crammed full of ideas and is an enjoyable enough way to spend an hour and a half. Despite its budgetary limitations, the sets and the special effects are excellent. Good fun. 3 out of 5
