The four-inch-tall Clock family secretly share a house with the normal-sized Lender family, "borrowing" such items as thread, safety pins, batteries and scraps of food. However, their peaceful co-existence is disturbed when evil lawyer Ocious P. Potter steals the will granting title to the house, which he plans to demolish in order to build apartments. The Lenders are forced to move, and the Clocks face the risk of being exposed to the normal-sized world.
There are several moments where Potter or the exterminator bang holes through the walls with a hammer (to get to the will or Arrietty and Peagreen).

Peagreen finds himself on an assembly line stuck in an empty milk bottle that's about to be filled. Arrietty and Spiller try to rescue him throughout the various stages of that filling process. Younger kids may get nervous as the bottle fills up with milk and a cap is put on, trapping Peagreen under the milk's surface. Meanwhile, Potter smashes bottles as they come down the assembly line and gets closer to hitting the one on which Arrietty and Spiller are standing.
