Unidentified season 
- Theorizing that one could time travel within his own lifetime, Doctor Sam Beckett stepped into the Quantum Leap accelerator - and vanished. He awoke 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 Doctor 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.
- Opening narration, Seasons 3-5 and syndication
- Theorizing that one could time travel within his own lifetime, Doctor Sam Beckett led an elite group of scientists into the desert to develop a top secret project, known as "Quantum Leap". Pressured to prove his theories or lose funding, Doctor Beckett prematurely stepped into the Project Accelerator and vanished. He awoke to find himself in the past, suffering from partial amnesia and facing a mirror image that was not his own. Fortunately, contact with his own time was made through brainwave transmissions with Al, the Project Observer, who appeared in the form of a hologram that only Doctor Beckett could see and hear. Trapped in the past, Doctor Beckett finds himself leaping from life to life, putting things right that once went wrong and hoping each time that his next leap will be the leap home.
