In an unspecified future, in unspecified woods, some solar-powered camera devices, left by documentary filmmakers, are activated with motion sensors. The documentary filmmakers are dead, almost all humans on the planet are dead, and the animals are alive. A man, now facing the end of his species, sends a voicemail to his best friend for the first time. The camera devices keep rolling. 

[Francesco Clerici, Director​]
