⚠️ Content Warning
Before anything else: this film contains graphic scenes involving death, suicide, and blood. The depictions are explicit and repeated throughout the movie. If you are sensitive to gore or themes of self-harm, this may be deeply triggering. Please approach with caution.
Plot**
The film opens on what should be an ordinary end-of-term school day. A student brings a DVD to class and plays it for everyone. What begins as a strange montage of chaotic images and distorted sound quickly takes a horrifying turn. At the end of the video, the same student suddenly jumps out of the classroom window to their death.
The class is left traumatized but the nightmare is only beginning. Their teacher informs them that they have been hypnotized. The DVD contained **100 hidden signals**, each capable of triggering them to commit suicide. In order to survive, they must identify and neutralize all 100 signals before they activate. From this moment onward, the film transforms into a psychological survival game.
The movie strongly echoes the survival chaos of **Battle Royale** and the high-stakes absurdity of **As the Gods Will**. Adapted from a manga, it carries that signature intensity exaggerated stakes, rapid escalation, and stylized brutality.
Japan has a long history of producing compelling survival thrillers, and this film continues that tradition. It blends psychological horror with graphic physical violence, creating an atmosphere that feels both frantic and triggering! However, this is not subtle horror. It is loud, shocking, and intentionally disturbing.
The “100 signals” concept allows the film to explore multiple forms of death, and it does so in graphic detail. The gore is not implied, it is shown. Blood is frequent, and the suicide scenes are explicit.
For viewers who enjoy extreme survival narratives, this may heighten the intensity and realism. For others, it may feel overwhelming or excessive. This is not casual viewing!!!!
Despite the heavy material, the cast delivers strong performances. The emotional panic, confusion, and desperation feel believable, grounding the more extreme aspects of the plot.
A standout performance comes from **Kanna Hashimoto**. With every role I see her in, she becomes more impressive.
One of the most surprising elements of the film is its ending. As the credits rolled, I found myself unable to turn it off — completely absorbed by the theme song. **Carry On** by **YukaDD** is powerful, catchy, and thematically fitting. It contrasts beautifully with the intensity of the film, leaving a lingering emotional impression. I added it to my playlist immediately and it has stayed there ever since.
This film is gripping, intense, and unapologetically graphic. It will strongly appeal to fans of survival manga adaptations and high-stakes psychological thrillers. At the same time, it is not for everyone. The gore and repeated suicide depictions may make it a difficult watch for some. If you can handle extreme survival horror, you may find this film compelling and memorable. If not, consider this your warning.
The only reason I am not scoring this 10/10 it is because of the pace and how everything went by so fast! I wish this was a drama it would have give more time to explore the feelings, grief and the horror.
