Director Oriol Paulo writes the script first, write the beginning and end, and then find a key node in the middle of the film. In "During the storm", the key point in the middle of the story is that the heroine Vera went to school to find her daughter but did not find it. Paul wrote the beginning, end and three plot points in the middle of the film, and then all the plots he could think of The details are written on small notes, plastering the entire wall of the studio. Finally, the director had to connect these small notes in series, sort out the timelines that appeared in time and space and the past time and space, so that these timelines should not be confused. The entire script was created for a year and a half, and 13 drafts were revised before and after.
Because the movie involves parallel time and space, Oriol Paulo specifically consulted relevant physics professors and read some books on quantum physics to prevent plot loopholes in the script creation stage. After writing the script, the director showed it to some friends and teachers who were police officers around him, but they did not find any logical bugs
