Struggling manga author Satoru Fujinuma (Yûki Furukawa
) lives with his mother and works part time delivering pizza. He occasionally experiences something he calls a "revival," in which he's thrown back in time a few minutes in order to stop something bad from happening.
When he comes home one day to find his mother has been stabbed to death in their apartment, he goes on a revival back to the time of his boyhood days, when three school children were kidnapped and found murdered. He befriends the first of the three to go missing in an attempt to stop it from happening and as a consequence, possibly stop his mother's murder as well.
