The eagerly awaited series has returned, taking place 30 years after the events of the first Quantum Leap on NBC, in which Dr. Sam Beckett (Scott Bakula) vanished into the experiment. The new show will use a similar format, with Dr. Ben Song (Raymond Lee) as the lead character who must body-hop through time and space. While each episode will be distinct, it will also examine the initial Quantum Leap experiment and the disappearance of Dr. Beckett. The cast has piqued the interest of observers.

The head physicist for Quantum Jump, a top-secret government time-travel project, Dr. Ben Song, takes an unauthorized leap into the past and awakens in a different body with just fragments of his memory intact. This is the story that centre the show. He learns that, thanks to Addison, a colleague who creates it so that it appears to him as a hologram that only he can see and hear, the only way for him to leap again is to resolve something similar in the life of his host person.
