Puck

A man in a dark outfit and red cap stands on an indoor ice rink, repeatedly swinging a large, black, curved blade to strike a line of black cylindrical objects arranged on the ice. He moves from right to left across the frame, then returns to the right, repeating the swing. The setting is a large, brightly lit indoor ice rink with white walls, a high ceiling with exposed metal trusses, and a row of benches along the left side.
