Yes Sir, I Can Boogie

The story

In the cradle of regional folklore, Zapruder stages a dance marathon with a cash prize for the last couple remaining on the floor. The rules: 1) the dance will take place in 3 consecutive runs; 2) the last session will continue to the end, until the dance floor has been cleared; 3) the music will be broadcast through earphones only and only for the dancers, who will dance on a stage wired with microphones and amplifiers. The dance floor will be the set for a film project.
