(Mad) scientist (Keir Dullea) gives him the chance to "see" again using radar sensors hidden in a Walkman which feed into his brain. Although all he can "see" looks like an early 1970s video game, he is able to function again. He crosses paths with the serial killer, who has even disposed of Marina Sirtis, and begins a hunt for him. Can he catch him before the maniac kills Rachel?
Really this is two films, the amateur surgeon serial killer, and the story of how Jonathan loses and regains his sight. Both films are interesting, even pretty good. Unfortunately when they are put together it all becomes a bit of a mess. It is slash gore horror meets Tron, worth seeing mostly for curiosity value.
