Strange look at gears and cogs in close-up.
Titles read: "Just Gears! And what gears there are - little ones, big ones - thin ones, fat ones, cams, cranks and connecting rods... all producing motion in a ---------- ways."
Location of events unknown - film could originate from France.
Various C/Us of cogs turning and machinery running. Some of them look quite bizarre and abstract; the final one looks like a snake falling down some stairs!
