context: The film starts with an aerial image of a boy rowing with his dog in a boat on the Ottawa River. The movement then freezes and the view slowly zooms out, revealing more of the landscape all the time. The continuous zoom-out takes the viewer on a journey from Earth, past the Moon, the planets of the Solar System, the Milky Way and out into the far reaches of the known universe. The process is then reversed, and the view zooms back through space to Earth, returning to the boy on the boat. It then zooms in to the back of the boy's hand, where a mosquito is resting. It zooms into the insect's proboscis and on into the microscopic world, concluding at the level of an atomic nucleus. It then zooms back out to the original view of the boy on the boat.
