One evening, while her parents go out for dinner, 18-year-old Louise, alone in her hotel room at Taj Mahal Mumbai, hears strange noises out in the corridor. Within minutes, she realises that a terrorist attack is underway. Her only connection to the outside world is her cell phone, which allows her to maintain contact with her father, who is desperately trying to reach her from the other side of a city that has been plunged into chaos. Louise must spend a long night alone in the face of danger. She will never be the same again.
