Non riattaccare

About this title

It's one of the many anonymous nights of quarantine when Irene's phone rings. It's Pietro, her ex. Irene hasn't heard him for months, since their story ended, she hesitates, but in the end she answers. Pietro is beside himself and his confused words suggest a desperate act. Irene just has to travel, to a ghostly city, without ever hanging up, with the hope of reaching him in time.
