The discovery of a black box lost in the Anthropocene era brings back to life extinct sounds images of places in the middle of nowhere voices of daily life and excerpts of conversations. The experience of an observer who from an indeterminate future finds evidence of a multimedia human kind develops along the trails which it leaves behind itself through multiple different supports and codes. The postmodern human kind is laid bare by apparently disconnected flashbacks which reveal the inappropriateness of a technologically advanced human species yet one unable to live with itself and with the world hosting it. Primordial instincts and feelings seem to be the only possible support to avoid decadency. Intellect technology and complex socioeconomic structures unsuitable to integrate with nature are unable to carry out the task of maintaining the balance of the planet.
