The video satirizes a popular conspiracy theory that the 1969 Moon landings were faked, the footage having been directed by Stanley Kubrick, and that Kubrick then made references to the fakery in various of his subsequent films.
In the video, a rock band similar to the Beatles (played by the members of Imagine Dragons) pretend to be astronauts for the faked moon landing. The taping goes awry as fans of the band stream into the sound stage and turn the event into a rock concert, much to the chagrin of Kubrick and President Richard Nixon, who is also on hand; though no one else watching, either in the studio or at home, seems concerned about the revelation of fakery, instead enjoying the music.
