Yusuke Kafuku, a stage actor and director, is happily married to Oto, a screenwriter. The couple constantly tell each other ideas for new stories that they come up with. However, Oto suddenly dies after leaving behind a secret. Kafuku withdraws from social life. Two years later, Kafuku, still unable to fully cope with the loss of his wife, receives an offer to direct a play at a theatre festival and drives to Hiroshima with his car. There, he meets Misaki, a reticent woman assigned to become his chauffeur. As they spend time together, Kafuku confronts the mystery of his wife that quietly haunts him.
"I first came to know this short story because when it came out in 2013, a friend of mine said that it was quite close to what I do in my work. And it was true: the fact that there was a car moving around and that you could have these intimate conversations coming up slowly in this closed-off space. /.../ But I think that the main interest for me was these strong characters, Kafuku and Misaki. They are very interesting. They are people that don’t really reveal a lot of themselves and only slowly come to talk about themselves." (Ryusuke Hamaguchi)
