Various shots of two young men living in a sealed plastic tent for 24 hours to test out a new life support system. The tent is inside a factory or warehouse. One of them lies on a bed, the other is Peter Newman, who looks at oxygen dials on the support system box.
Outside the tent a woman looks at a meter that is measuring the heartbeats of the men and makes notes. C/U of the life support box inside the tent. One of the men makes tea with an electric element in a cup. The woman outside starts up a metronome. Peter Newman does exercises in the tent.
Finally the tent is opened and the pair come out. Photographers take pictures as the men do some knee bends and arm stretches.
