One morning, on a commuter bus, a female passenger grabbed a man who was molesting a schoolgirl, stopping him. Six months later, that same man reappeared on the bus. The woman gasped in shock. At that moment, another man pulled a knife on the driver and took all passengers hostage. With their cell phones seized, communication with the outside world was cut off. The female passenger murmured, "I've always wanted to openly get away with molesting someone once." What fate awaits her now that she's trapped in this hijacked bus?
