"Quantum Leap", the time travel science fiction TV series, originally created by Donald P. Bellisario, has been renewed for Season Two on Peacock: :
"...30 years after 'Dr. Sam Beckett' stepped into the 'Quantum Leap' accelerator and vanished, a new team has been assembled to restart the project in the hopes of understanding the mysteries behind the machine and the man who created it..."
"...in the original series, physicist 'Dr. Beckett' (Scott Bakula) theorized that time travel within one's own lifetime is possible, and obtains government support to build his project 'Quantum Leap'. But years later, the government threatens to pull funding, as no progress has been made, and Beckett decides to test the project accelerator by himself to save the project before anyone can stop him. He is thrown back in time, and on regaining consciousness, finds that while he physically exists in the past, he appears to everyone else as a person into whom he had 'leapt'.
"A hologram of his friend 'Admiral Al Calavicci' (Dean Stockwell) appears, visible and audible only to Beckett and explain that Beckett must correct something that went wrong in the past, aided with the resources of the project's supercomputer 'Ziggy' (voiced by Pratt).
"Despite successfully 'correcting' the past, Beckett continues to leap randomly to another place and time within the second half of the 20th century, putting right what once went wrong and hoping each time that his next leap will be the leap home..."
