Filmed in a minimalist white space, perhaps with a few objects suggesting a street setting
One figure joins the back of a long line of people and waits impatiently. Meanwhile, somewhere else in the same long line, someone else is also waiting for his turn.
As the video progresses, it's revealed that both dancers are actually in an infinite line made up of just the two of them, alternating forever.
From this starting place, the video builds choreography out of repeated movements of the two men:
looking back at the guy behind you
trying to cut out of line only to be blocked by the man in front doing the exact same thing
tapping the man in front on the shoulder, only to be tapped on the shoulder by the guy behind you.
We build from mundane movements to full choreography
