Work!

Three men work on a brick building under construction, with one man on scaffolding holding a tray, another man on the ground mixing cement with a hoe, and a third man on the ground mixing cement with a shovel. The man on the ground repeatedly scoops and throws cement up to the man on the scaffolding, who catches it in the tray. The scene repeats in a loop. The setting is an outdoor construction site with trees and a partially built brick wall.
