Oblivion Song (1970)

Based on Robert Kirkman and Lorenzo De Felici’s sci-fi comic book series. The story takes place one decade after 300,000 residents of Philadelphia were suddenly trapped in Oblivion. Frantic recovery efforts were launched by the government but, after a few futile years, they were abandoned. Nathan Cole, however, hasn’t given up. He risks his life again and again trying to save those lost souls in Oblivion’s apocalyptic hellscape – but is that the real reason he can’t resist the siren call of the Oblivion Song?
