The full film is fairly intense.
People start to believe a fictional story of aliens is really happening go into mass hysteria, which is all fairly intense and somewhat frightening.
People pack there houses and flee the city.
A man assaults a police officer out of fear and gets arrested.
A priest locks himself in his church thinking he will be safe.
A radio broadcaster says that a woman had poison and said I would rather die this way not shown, but heard.
All in all this a very good plot line and an amazing story but a very frightening and disturbing plot line of Mass Hysteria.
