The movie did not have a complicated storyline but it was filmed in such a way that made the viewers feel anxious and stressed, so everyone would feel extremely uncomfortable while watching the movie.
The terrorists depicted in the film was part of a branch of a famous terrorist organization from a particular country and they were extremely evil and cunning. They had captured 72 students and held them as hostages and demanded the country give them land and resources and to withdraw the troops all meant for anti-terrorism operations from Country S. If the country refused to meet their demands, they threatened to kill one hostage each day and said that they would use the most ruthless methods to kill them.
The entire film was both terrifying and gory. The ruthless terrorists and the terrified cries of the children would make the viewers feel very upset.
