Once again, Michael Rennie dons a tin-foil suit to come and warn mankind to amend it's ways. This time, though, he is a cyborg called "Garth 7" sent back from the year 2087 to try and stop an evolutionary process that will rob us all of our ability to think for ourselves. He manages to ally with "Dr. Mason" (Karen Steele) but pretty soon they are aware that the government they wish to thwart has also sent agents back and so not just time, but other folks from the future are against them too. This is cheap and cheerful, pedestrianly written, afternoon fodder that is very light on science or characterisations. Rennie looks like he maybe only did the one filming day, such is the truncated nature of the editing - and the special effects (his bio-implants, especially) are not up to very much, either. Oddly enough, it might have looked better in black and white, somehow the colour just makes it look even more sloppily thrown together. Potentially, an interesting take on a well used idea, but sadly it offers little we haven't seen before and the star is well past his best.
