How Long Is “The Cage”?

A soundless film starts in a studio: an artist sits, a nude stands; a page burns, paper cutouts appear, images are distorted. The artist removes his eye; it falls from his hand, seeing images spin as it rolls. A man falls, objects in the studio falls on him, he's not the artist. A woman gets help from a man in a lab coat; he and the man on the floor fight over a shotgun. Outside, in the city, people and cars move backwards. On the street, those from the studio chase a woman who's stolen leeks. In the backward cityscape, they move forward. They run toward a seaside amusement park. The artist follows, his head in a bird cage. He ends up with the woman who went for help; or does he?.
