Satoru Fujinuma is transported back few minutes before an accident occurs when catastrophe is about to strike. The estranged 29-year-old manga artist has used this strong yet inexplicable phenomena, dubbed "Revival," to rescue numerous lives. However, when he is wrongly accused of murdering someone important to him, Satoru is thrown back in time, this time to 1988, 18 years ago. Soon after, he concludes that the murder may be linked to the kidnapping and murder of one of his classmates, the isolated and enigmatic Kayo Hinazuki, when he was a child. This is his opportunity to put things right.
