In the opening shot, there is a tiny ball of light, which turns into a bright circular flash, slowly coming into view with a circular object. Amidst the ominous tone that plays, we hear a woman's voice making sounds, trying to get her speech down to being perfect.
We see what appears to be a black liquid circular pool. The light and the circular object come together to form an eye - a mysterious woman's eye. A shot of a long curving road between the mountains of Scotland with a single headlight appears.
The view changes and we see it is an unknown man on a motorcycle. The man rides his motorcycle to a tunnel where he stops. He gets off the bike and walks off the road into a ditch, appearing a moment later carrying a young woman's body.
He throws the body into the back of a white van. Next, we see the woman's dead body being unceremoniously undressed by another naked young woman in a white, brightly lit room. After the woman is dressed, she stands over the body and stares at it.
The camera focuses on the now nude woman's body and we see a tear fall from her eye - we are not sure at this point if she was indeed dead, and the tear was simply a reflex, or if she is perhaps in some catatonic state.
The identity of this woman remains unknown throughout the film, but due to the tear falling, and due to the motorcycle man knowing exactly where the body was, she may have been in some sort of comatose state and aware of what was going on. The woman who took the clothing bends down over the body and seems to inspect something she picked up from the body. It appears to be an ant that was crawling on the dead/comatose woman's body.
The next scene opens with a cloudy sky and mysterious lights above a tall skyscraper. This scene is supposed to be the indication that it is an alien presence that the film is depicting, although this particular scene is brief. The mysterious female is then seen leaving a dirty rundown looking house. The white van is parked outside, and the motorcycle man is there as well. The relationship between the two is unclear at this point, although they seem connected.
These two, although seen together in a few scenes, and often in the same areas, do not communicate at all in the film, leaving us to assume they communicate telepathically or some other way. The man departs on his motorcycle, and the woman gets into the white van and begins to drive. Later, the mysterious young woman/alien is seen in a crowded shopping mall. She seems to pick out several items of clothing including a faux fur coat and red lipstick.
She then continues to drive in the white van, eyeing men as she drives past. She passes through several crowds of people before stopping on a less crowded street to approach a man who is alone, like any good predator would. She asks him for directions and they converse. Several separate scenes repeat the same pattern- she seeks out lone men walking and asks for directions or some other banal topic.
