Night Wanderer

4400 centers on the return of 4400 people who, previously presumed dead or reported missing, reappear on Earth. Though they have not aged physically, some of them seem to have deeper alterations ranging from superhuman strength to an unexplained healing touch. A government agency is formed to track the 4400 people after one of them commits a murder.

Time Trax is an American/Australian co-produced science fiction television series that first aired in 1993. A police officer, sent through time into the past, has to track down and return convicted criminals who have escaped prison in the future. This was the last new production from Lorimar Television.

"Ever wish you could live your last week all over again? Well, my name's Frank B. Parker, and I do it all the time. I work for a secret government project experimenting in time travel. When things really get screwed up, I'm the guinea pig they send back to take care of it. The catch is, I can only go back 7 days."

Theorizing that one could time travel within his own lifetime, Dr. Sam Beckett stepped into the Quantum Leap accelerator and vanished... He woke to find himself trapped in the past, facing mirror images that were not his own and driven by an unknown force to change history for the better. His only guide on this journey is Al, an observer from his own time, who appears in the form of a hologram that only Sam can see and hear. And so Dr. Beckett finds himself leaping from life to life, striving to put right what once went wrong and hoping each time that his next leap will be the leap home.
