The clip, which was shot over 15 hours, sees the Surrey-based rock group under interrogation after being arrested "for being a band".
Singer Josh Franceschi said: "The whole concept of our album is being under arrest... whether it be body arrest or not being able to say what you want to say, when you want to say it.
"Throughout the video we're getting interrogated by these two guys... basically we've been arrested for being a band."
'Loverboy' - out September 25 - marks the first release from the group's third studio album Sinners Never Sleep, which follows on October 3.
