Scientist Dr Nelson (Robert Lansing) is working on advanced new materials, he discovers that radiation has mutated him so he can now pass through solid matter.
However, every time he does this he ages rapidly. To counter this he must kill people to rejuvenate himself through their life force. It falls on his brother Scott (James Congdon) and his girlfriend Linda (Lee Meriwether) to try and find a way to stop him...
This is a rather decent example of the 50s/60s "science gone wrong" science fiction genre. Although the story takes some time to get going, once it does it is engaging and the special effects are pretty well done especially for their day. The jazz soundtrack is rather jarring though but somehow kind of works?
