Passengers cope with the grim situation of being hijacked on a suicide terrorist mission, and ultimately they decide to foil the marauders even at the cost of their own lives.
Some quick slashings with box-cutter knives (some blood shown), and a man is splashed with boiling water. The worst is left to the imagination.
Hardly any rough language.
Even the aircraft insignia are left out, though soft-drink labels show on a beverage cart being used as battering-ram.
