Enrico, Renato and Federico go on to events. Inaugurations, concerts, light shows. They are friends and roommates, they share an apartment where there is also a fourth subject, a musician. But he is as if he did not exist, not because he is always on tour, far from it: a year ago he chose to live as a hikikomori, that is, like those Japanese teenagers who barricade themselves in their bedroom and no longer come out. Only that the boy in question is no longer a boy, but an over thirty year old like the other three. Will our heroes be able to shake off the unbearable lightness of a life that shows backlight all the cracks and cracks in a society where fun at all costs is nothing but a carpet under which to hide their dissatisfaction?
