How did quantum leap start (how did the guy get trapped in other people's bodies) and how does it end?

Answer 1

In the near future (about 1995), at a highly classified U.S.-government-funded research facility somewhere in the desert of New Mexico, physicist Sam Beckett (Scott Bakula) is working on a grand experiment to prove his time-travel theory. Sam is working alongside Gushie, the lead programmer of Project: Quantum Leap. Gushie also works the controls for the imaging chamber. However, the funding for the project is about to be cut. Sam's colleagues protest that they're not ready, but in a last-ditch effort to prove that his theories are correct, Sam steps into the project's "accelerator chamber" and vanishes.


Dean Stockwell & Scott BakulaSam appears in the past with no memory of who he is or where he is. This side-effect of uneven amnesia is called Swiss-cheesing or (as a technical term in the show's universe) magnafluxing, which prevents him from remembering most of the details of his own life. His friend from his original time, Albert "Al" Calavicci (played by Dean Stockwell), appears to him as a holographic projection from the "imaging chamber", usually only visible and audible to Sam, but also small children, and animals. Al is the project observer and a retired U.S. Navy Rear Admiral. It is revealed that Gushie made a frantic call to Al when Sam vanished in the imaging chamber and called him in to work on the situation. Gushie continues to work alongside Al in Sam's original time. Along with the (possibly) sentient supercomputer named Ziggy, Al is able to help Sam "set right what once went wrong" before he leaps out into the next person. At the beginning and end of nearly every episode, as Sam leaps into a new person, the catch phrase of "Oh boy..." is uttered.
DR Sam Beckett got into the quantum time machine before it was fully tested. To make room for him in the time he travelled to the person he became was transported to his (Sam's) time. Sam would then be responsible for mending the rift in time by correcting what was wrong. He would only transport to a time in his own lifespan where there was a mistake in time to correct. His friend Al would travel to help Sam, but Al was only a hologram. Gushie and Ziggy were contacted via the hand lin that Al carried and would give Al statistics and probabilities about the possible solutions that would cause Sam to leap again.
Sam always had the capability to return home it was explained. He never did return home and is still leaping I guess.
...so Al went back to the wife he lost in the past.
...Sam left the wife he had in the future.

Answer 2

He (sam beckett) was a present day scientist, who designed a machine for the purpose of travelling back in time and into other peoples bodies in the hope of avoiding tradgedys about to befall them.
The ending was slightly disappointing as far as i am concerned, it was an eposode were he meets a man who maybe god, it was a long time ago and i don't remember all the details, but in the finish we the viewers are told that he carried on with his time travelling and that he never got his wish of returning home.

Answer 3

Theorizing that time travel within one's own lifetime was possible, Dr. Samuel Beckett stepped into the Quantum Leap accelerator... and vanished.

Answer 4

Not sure how it started, but the main guy meets "god" at the end. He never makes it home; he must continue helping people forever. Mac or Max, whatever his buddies name is, gets to go back and be with his young wife. She thought he died in the war. This is all I remember and I think its accurate.
