Matsuda plays the role of Kase Shinji who has the habit of going on daily walks every evening but disappears without a trace for a few days. When he returns home, it is as if he has become an entirely different person which makes his wife Narumi shocked at his changes especially when he becomes very gentle and nice to her. Suddenly, Shinji tells Narumi that there will be an attack on Earth which is then followed by a series of strange happenings such as the mass killing of a family in the town they live in and the happening of weird events that disrupts the peaceful life they once had. Hasegawa plays the role of a journalist Sakurai who follows the "invader" around as part of his job.
Nagasawa who was impressed with the script, expressed deep interest in the movie and commented that she can identify with Narumi's feelings as a woman and hopes to be able to convey the love she has for Shinji as a family. Matsuda said that he is thankful for Nagasawa's efforts and revealed that Shinji was a tough character to play as he was angry all the time and it has been a long time since he felt giddy every day on set due to the emotional rollercoaster he had to go through. As the presence of the invader poses a threat to the relationship between Narumi and Shinji which was already shaky before his disappearance, Matsuda commented that he had to show how Shinji tries to make things work again between them and show the difference between the original Shinji and the invader's characters. As there are many elements in this movie, he thinks that it will be an interesting film which will attract people of varying tastes.
Hasegawa revealed that before the filming, the director had told him to forget about his past roles so as to act in a new way for Sakurai. Besides the romance element, the friendship between men is also something to look out for in this movie.
Filming was done over a month from late July. The movie will be shown in cinemas from 16 September 2017.
