In a London clock shop, the owner finishes business up for the day and turns off the lights at goes to the back. The clocks are revealed to be alive, and have personalities. One clock, a little green one with a silly figure of a man on it that rings the bells and reveals his underwear after ringing the bells, is bullied by the other clocks. It is pushed off the shelf it sits on and lands on the counter, where the watches laugh at it. Indignant, the little clock tries to remove the man through various means, but to no avail.
Suddenly, a burglar approaches the door. He breaks through the glass window with his fist and unlocks the door. The frightened clocks quickly freeze in place, and the green clock hides behind the cash register. The burglar takes some clocks and puts them in a sack. He is about to leave when he sees a policeman walking on the bridge nearby. After the policeman passes, the burglar opens the door and goes to his car. The green clock quickly rushes to the door and manages to keep it from closing by jamming the little man between the door and the door frame. It exits and stands triumphantly - only for the bells to ring. The burglar hears the bells and smashes the little clock off-screen, to the horror of the other clocks. The policeman hears the burglar and tells him to stop, but he runs. The policeman chases after him, leaving the little clock lying on the ground.
The next day, the policeman finishes explaining to the owner and walks away. The owner picks up the green clock and takes it inside, where he drops it in the wastebasket. He sits down to work when suddenly, he hears a sound. He looks out to see the wastebasket empty. The green clock is lying on the counter, with a sign next to it that says "No repair is too small." The owner smiles and decides to fix the clock.
After finishing the clock, he places it back on its shelf and removes the sign below it that reads "75% off - runs slow". The owner leaves for the night once more. As the clocks come back to life, the big clock that had bullied the green clock opens the glass case and sets the time properly. As the little clock rings joyfully, all the other clocks join in.
