It's been nearly 30 years since Dr. Sam Beckett stepped into the Quantum Leap accelerator and vanished. Now, a new team, led by physicist Ben Song (Raymond Lee), has been assembled to restart the project. Everything changes, however, when Ben makes an unauthorized leap into the past, leaving the team behind to solve the mystery of why he did it. At Ben's side throughout his leaps is Addison (Caitlin Bassett), a decorated Army veteran who appears in the form of a hologram only Ben can see and hear.
The new Quantum Leap sequel takes place 30 years after Dr. Sam Beckett disappears into the Quantum Leap accelerator and centers around a new character, Dr. Ben Song, played by Raymond Lee. Fans of the original Quantum Leap are in for a few surprises, including the return of some original characters and the continuation of the most popular plot points.
The Quantum Leap project has been restarted with a new team trying to piece together the mysteries behind Beckett and his machine. For reasons unknown, Dr. Ben Song, the new project's lead physicist, has uploaded new program code to the project systems and used the upgraded accelerator to leap back in time.
