365: Repeat the Year

365: Repeat the Year follows a group of ten individuals who are given the mysterious opportunity to 'reset' their lives by traveling back in time exactly one year. Led by a psychiatrist named Lee Shin, the participants hope to fix their past mistakes, prevent tragedies, or simply gain a better future. Among them are Ji Hyung-joo, a veteran homicide detective seeking to prevent the death of his partner, and Shin Ga-hyun, a successful webtoon artist whose life was shattered by a hit-and-run accident. However, the group soon discovers that the 'reset' comes with deadly consequences. As the participants begin to die one by one under suspicious circumstances, Hyung-joo and Ga-hyun team up to uncover the truth behind the time-slip phenomenon. They must navigate a web of betrayal, hidden agendas, and the terrifying realization that altering fate may be more dangerous than living with the original consequences.
