Aglaé, a young factory worker, has only one focus in life: her job at a car crash test site. When she learns that the factory is going to be relocated abroad, she accepts, to everyone's surprise, to go to India in order to hold on to her job. Accompanied by two colleagues, she sets out on a perilous road trip to the other side of the world.

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.
