"Quantum Leap" is a science fiction series aired in 1989-93. The mother play tells the story of physicist Sam Beckett (Scott Bakula) who carries out a time travel research project called "Quantum Jump" with government support, but when there is no progress and is ready to be withdrawn by the government, Sam decides to go into the accelerator to test it. Unfortunately, the experiment is not completely successful, although the protagonist successfully carried out time travel, but the jump point is not controlled, and will continue to jump. The restart version tells the story of 30 years after Sam Beckett stepped into the accelerator and disappeared, and now a new team is about to restart the project, hoping to understand the mystery behind it. Scott Bakula will not participate in this project.
