During a government experiment into time travel, a scientist finds himself trapped in the past, "leaping" into the bodies of different people on a regular basis and sorting out their problems whilst trying to get back home to his own time.
Sam leaps into a bar with a bartender that's more than he appears. When Sam looks into a mirror, he sees his own reflection. In the future, they realize that Sam has leaped into himself, they search ...
Theorising that one could time travel within his own lifetime, Dr Sam Beckett stepped into the Quantum Leap Accelerator, and vanished. He awoke and found 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.
Donald P. Bellisario established Sam Beckett's birth year 1953 by reversing digits of his own birth year 1935. However, in season one, episode five, "How the Tess Was Won", after Al tells Sam that it's 1965, Sam replies that's he was ten in 1965. See more »
In the Season 5 opening, "Theorizing that one could time travel within his own lifetime...", the visuals reflect the narration. The narrator says, "Dr. Sam Beckett stepped into the Quantum Leap accelerator and vanished...", what is seen is him leaving the imaging chamber after leaping back to New Mexico. See more »
the Devil (as Al):
What gives you the right to leap about time, putting right what I made wrong.
I'm just trying to get home.
the Devil (as Al):
Well, you're not going to make it!
