Every elementary particle we know has an opposite particle that has exactly the same characteristics, except for the electric charge, which is the inverse. The positron, for example, is the electron's antimatter, therefore, it has the same mass, same rotation, same size, but an electric charge of opposite sign. In these dark times, what will be the antimatter of each human being? Perhaps it is in a parallel world where the problems of this time no longer exist? A virtual meeting performance between two artists, Nina Marqueti, a Brazilian living in New York, and Pedro Vicente, a Brazilian living in Lisbon. Through the benefits of the internet the two interact in a performance that transits between Lisbon, New York and Amsterdam.
