RETSU (The Line) is a Japanese short film built around a simple but unsettling mystery: a man suddenly discovers that he is standing in a line with no visible beginning or end.

The central figure is a biologist pursuing research into ape intelligence while hoping to make a historic discovery. His unexplained place in the queue turns that personal ambition into a broader question about life in a society shaped by constant comparison.

RETSU (The Line) movie details

Story without spoilers

The film centers on a biologist who finds himself in a strange, seemingly endless line. He has no clear explanation for how he arrived there, and the people ahead of him—a businessman, a woman in a purple dress and a young man wearing work clothes like his own—are equally uncertain about their circumstances.

There is also an uneasy sense of recognition among the group. They appear to feel that they may know one another, yet none of them can identify the connection. As they confront the mystery of the line, the story considers whether people can escape the social pressures that encourage them to measure themselves against others.

What to expect

The supplied premise points to an idea-driven short centered on a small group of strangers, with the biologist’s research providing an important part of the story’s context. Specific stylistic details, performances and ending are not provided.

Movies Dock view

With its unexplained setting and compact runtime, RETSU (The Line) frames social comparison as a literal problem: people are placed beside one another, yet do not understand why they are there or how to leave. The film’s appeal rests on that carefully defined premise and the questions it leaves open about human behavior.
