After making a speech to the world about a no-tolerence policy againgst terrorism, the president's plane is hijacked by terrorists.  This is an amazing film.  The plot is superb, and the action is great.  Harrison Ford is an astounding actor, and plays a president/father with super accuracy.  The stunts in this movie are great, including a scene with a refueling tanker, and a scene where the president must ride a tether to get out of the plane.
