Robots work on a dairy farm. They milk the cows, clean their dung, and massage them. Meanwhile, human beings are absent. In a restaurant, robot waiters bus food back-and-forth, ignored completely by their human colleagues. An engineer revives an old robotic arm for his children. With a curious, observational gaze, Metabolism looks at technology, animals, and labor.

Metabolism has recently received the Post Production financial grant from The Netherlands Film Fond.
