La guerra del Tiburtino III

About La guerra del Tiburtino III: In the Tiburtino III neighbourhood, in the outer suburbs of Rome, a small asteroid falls from the sky. In the following days, almost everyone in the suburb starts behaving inexplicably oddly: they all suck AA batteries. An improbable group of young characters finds out that many have been infected by some parasites and the aliens intend to conquer the whole world.
