365: Repeat the Year (Season 1)

365: Repeat the Year (2020) is a Korean mystery series you can watch online on iFILM. Ten strangers are offered a chance to rewind their lives by exactly one year and undo their worst mistakes. It sounds like a gift — right up until the volunteers start dying one by one.

Detective Ji Hyung-joo, from the violent crimes unit, takes the "reset" without much hesitation; he has plenty he'd rather do over. But instead of a clean slate, the group falls into a web of eerie coincidences and deaths, as if someone already knows their every move. Hyung-joo starts pulling at the threads and realizes that going back was the easy part — fate doesn't like being cheated. Lee Joon-hyuk and Nam Ji-hyun anchor the cast, with Kim Kyung-hee directing.

It's adapted from Yusuke Kishi's Japanese novel Repeat, and it keeps that puzzle-box build: each episode hands you a fresh victim and a fresh theory. One tight, self-contained season, no filler. Best for viewers who like time-loop thrillers where the riddle matters more than the romance. Stream 365: Repeat the Year online on iFILM.
