Plot

It starts out with a man watching women in an exercise video dance on a window TV in a store.

A worker at an automotive manufacturing plant remotely operates large robotic machinery on an assembly line. As he heads home from work one night, one of the machines seems to be on the loose, following him, although no one else can see it. He tries to ignore repeated menacing appearances of the machine outside of the plant, but its focus on him is unwavering, until he finds himself cornered in a final confrontation.

In a brief prologue, a man watches an aerobics TV program in a window display at a store, which ends with one of the women in the video shouting at him directly, which startles him. He arrives at his job at an automotive manufacturing plant, where he remotely operates robotic machines that handle assembly line tasks. As he heads home after work on a sidewalk along a river, however, he encounters a machine similar to those at his job: a large apparatus capable of walking on three mechanical legs, with a massive claw at the end of a long arm in place of a head, and it appears to recognize him. He quickly turns and heads the other direction. As he runs a bath at home, the giant claw smashes through his bathroom window; however, he quickly wakes up from a dream, and confirms that his bathroom window is intact. The next day at the plant, he watches many machines assembling cars, just like usual. As he heads home, the machine is loose in the park; he keeps walking. As he gets takeout, the machine is waiting outside for him; he tries to ignore it. He confides in a manager the next day, who sends him home, and on the bus ride home, the machine chases him along the route. He boards a subway car; as the train leaves the station, the machine barrels around the corner and almost catches up to him. The machine is waiting for him as he exits the subway and chases him through the streets; he is clearly the only person who can see it. Finally he escapes to the top of a parking garage, believing he is safe, but the machine climbs the side of the garage and confronts him. He breaks down in tears as the machine moves in for the kill, but just as its giant claw begins a downswing toward his head, it disappears. He staggers back out onto the streets, which are now completely devoid of other people. But there are multiple machines approaching from three directions at an intersection, at least a dozen charging his way, and he falls to the street laughing hysterically. In the end, he is alone; there are no machines, nor people, anywhere in sight.
