"Nine: Nine Time Travels" invested 5.9 billion won in production costs and is the largest TV series in the history of cable channels. 38-year-old Park Sun-woo (Lee Jin-wook) is a successful reporter with 12 years of experience at CBM TV.

Those seemingly ordinary incense sticks turned out to be mysterious kits that could go back to 20 years ago...
