A daily journey under the capital's ground seen through a microscope. Despite the high numbers of coronavirus contagion, the urban network must continue to function and circulate. The underground air of the subway condenses and allows the invisible virus to be glimpsed among the passengers, the nervous hands that touch everything and nothing at the same time, the noses escaping from the masks. A new body choreography that begins to reveal itself, inserted in a disjointed present that yearns for the functioning of an extinct normality.
