We are in the future (2073) and mankind is sending probes back through time (quite why we don't know especially as it ends up being so dangerous). Scientist Sinclair (Richard Keats) sends a probe robot though to 1973 where it encounters a couple in a caravan and immediately trouble begins. Sinclair goes through time to make sure the robot self-distructs... but when he returns to 2073 he finds everything has changed.
2073 is now a post-apocalypse wasteland where killer robots slaughter the battered remnants of mankind. Sinclair, despite being now in a changed timeline, remembers his old timeline and seeks out his old lab to see if he can restore the timeline and see his beloved wife Natasha (Lisa Ann Russell) again.
An interesting film. Although it is rather cheap and the special effects a bit average (though the robots look good), this film isn't that bad. It has some good ideas and does a decent job to make the most of what it has to try and carry them out. The plots has some holes, but it seems so does time.
