I'm in the backseat of a smart, black car. Outside, a movie is rolling, all around the vehicle.
Tom Cruise is a character in a rocket suit speeding through the air above multiple freight containers. He's flying over enormous vessels. Together they are the size of a small city and each one is bearing rows of multicoloured containers. Things like flying train engines pull them through the sky.
Cruise speeds over them as fast as he can. Sometimes he disables the rockets so he can swoop down and fly between them, sweeping along corridors of metal.
He grabs parts of the structure in order to change direction, hauling himself up, or onwards, or down, firing up the rockets, shutting them off. His skill at flying is impressive. His determination is as breathtaking as his pace. It's like parkour with a rocket pack.
There are enemies amid the containers. It's Mission Impossible meets James Bond meets Iron Man. Cruise takes them out by flying into them or by hurling them over the edges of containers. He mixes martial arts with aerial maneuvers.
He must reach the head of the lead vessel before the clock runs out. Cruise's face is determined as he battles with gravity, inertia and enemy personnel. He is alert and, though he has a sense of urgency, he is relatively calm.
Exhausted, I fall asleep for what seems like a few minutes. When I wake, I look out of the window and the scene is still going on. It's the most amazing chase scene I've ever seen and I'm sort of in it. The heights are breathtaking and I feel a thrill as Cruise mounts containers and flies down, down, down the sides of stacks, free-falling in the midst of a great container city. The buildings are red and blue and yellow and green and there are lights blinking below to show highways and byways between the boxes. Watching the movie is as exhilarating and vertiginous as a roller coaster ride.
When I wake, I feel energised and capable of surmounting any obstacle with speed, class and grace, which is good, because the kids are crying.
