A man in a bright green shirt stands on a muddy construction site, repeatedly grabbing and releasing a heavy chain suspended from the bucket of a yellow Caterpillar excavator, which lifts and lowers the chain in a looping motion. The excavator's arm moves up and down while the man swings on the chain, eventually letting go and falling to the ground. The scene takes place outdoors on a cloudy day, with trees and a small wooden shed in the background.
