On a late-night train, seven passengers see a man harassing a woman but don't intervene for various personal reasons. The woman, Michelle, is later assaulted. The passengers face personal misfortunes connected to the incident. Haunted by visions, Angel eventually decides to seek justice. With the help of Michelle's ghost, the rapist is punished, and the passengers find some resolution.
The movie Pasahero explores the psychological (or sociological) phenomenon called the bystander effect-where people are less likely to help someone in need when others are around. Here, passengers on a train witness a crime but choose to stay silent, perhaps out of self-preservation.
