While You Were Sleeping

Even with her extraordinary gift, Nam Hong-ju has never been able to change the future. But with her mother's life at stake, she's determined to try.

Finding this déjà vu all too impossible to believe, Jeong Jae-chan brushes Hong-ju aside and attempts to adjust to his new role as a prosecutor.

Three people with the same mysterious ability converge at a crime scene. But that doesn't stop Jeong Seung-won from resenting his spineless brother.

After seeing a tragedy unfold in his dream, Han U-tak invites a different guest to dinner. Jae-chan finds more people to fight on his side.

Hong-ju debates whether to go back to work. U-tak comes up with a theory to explain what made him, Jae-chan and Hong-ju special.

Back at her old job, Hong-ju investigates a mass killing. Jae-chan comes head-to-head with Lee Yu-beom on a homicide case.

Hong-ju's heart grows heavy as she's unable to protect another loved one from danger. An old roommate pays U-tak a late-night visit with a request.

As Jae-chan interrogates Do Hak-yeong, he finds that the pieces don't add up for a conviction. Could it be that his only suspect is actually innocent?

Yu-beom pits the public against Hak-yeong, which means Jae-chan will have to search for irrefutable evidence that would put all suspicion to rest.

An old note stirs up repressed memories for Hong-ju as she remembers the day she almost killed a person out of spite. Jae-chan confronts his attacker.
