The video follows Bastille frontman Dan Smith, as he wanders about an empty-looking Los Angeles, before realizing the few people around all have unnatural vacant black eyes. He steals a car and drives into the desert to escape them, but the car breaks down and he soon realizes he's been infected as well. He climbs a mountain and looks out at the view, before turning around to reveal his own eyes have turned black as well. The story is an allegory for the eruption of Mount Vesuvius in Pompeii.
